1. The Castle Hill Wind Farm Project

Genesis Energy is proposing to construct and operate a wind farm in northern Wairarapa,

known as the Castle Hill Wind Farm (hereafter referred to as “CHWF”). The CHWF Site is

located 20km east of Eketahuna and Pahiatua, 20km north-east of Masterton and 15km west of

the Wairarapa coast north of Castlepoint (Figure 1, Appendix A). The CHWF Site covers an

area of approximately 30,000ha.

The CHWF Site is characterised by undulating hills of predominantly pastoral grass, with grazing

by sheep and cattle. Stands of native vegetation are located throughout the Site, particularly in

gullies, with several small forestry blocks scattered across the Site. The topography is varied,

with elevation ranging from 200m to 500m above sea level.

The CHWF Site is located in a remote area that is sparsely populated. There are six small ruralsettlements in or around the CHWF area including Tinui, Pongaroa, Alfredton, Makuri, Tiraumea

and Bideford. These six settlements had a combined population in 2006 of around 500 people

in 110 households1. Masterton (population 18,000), Pahiatua (population 2,600) and Eketahuna

(population 460) are the larger townships located within 30kms of the CHWF Site2 (Figure 1,

Appendix A).

Key components and features of the CHWF project include:

• Turbines: plant consisting of foundations, tower, nacelle and rotor for conversion of

wind energy into electricity.

• A Turbine Corridor: 3,144ha identified as suitable for turbine placement. Turbines

will be located within this corridor.

• Turbine Clusters: groupings of turbines for ease of reference.

• Turbine Configurations: up to 286 Medium Turbines (maximum tip height 135m) or

up to 242 Large Turbines (maximum tip height greater than 135m but no greater

than 155m) or a mixture of Medium and Large Turbines installed within the Turbine

Corridor.

• Internal Roads: roads constructed within the CHWF Site for transporting wind farm

components, materials and personnel within the Site and to allow access aroundthe Site for construction and operational activities.

• Electrical Balance of Plant (EBoP): All electrical structures and equipment related to

the collection and reticulation of electrical power around CHWF to the point of

connection to the External Transmission Line. Plant includes an Internal

Transmission Line, 33kV overhead lines, 33kV underground cables, a MainSubstation and Satellite Substation, an optional Switching Station and switch gear

huts along with other associated electrical equipment.

• Monitoring masts: up to 16 monitoring masts to collect on-going meteorological

information during the operational life of the CHWF.

• External Roads: Public roads near the Site that are planned to be used for traffic

associated with the construction and operation of the CHWF and by Over-weight

and Over-dimension Vehicles (OW/OD Vehicles).

• Earthworks associated with the construction and maintenance of the CHWF.

• Temporary construction infrastructure: components required for construction of theCHWF including Concrete Batching Plants, Central Laydown Areas, Excess Fill

Areas, Contractor Compound, quarrying and crushing facilities and water storage

and abstraction facilities.

• Operations infrastructure e.g. operations and maintenance buildings (O&M

facilities).

The Turbine Corridor, Turbine Clusters, Internal Roads, Substations and the Internal

Transmission Line are shown in Figure 2, Appendix A. External Roads are shown in Figure 3

(Appendix A), and wind farm components are shown on Figures 4, 5, 6, 7 in Appendix A.

The generation capacity of the CHWF is in the order of 600MW. The maximum capacity will be

dependent on the type of turbine eventually selected for the Site but current Site and wind

turbine analysis indicates a potential capacity of up to 860MW.

Development of the CHWF may progress in stages, with any first stage being in the order of

300MW. This capacity depends on the wind turbine model selected, but will also depend on

other commercial and technical factors.

2. Purpose and Scope

In applying for the resource consents to construct and operate the CHWF and associated

structures, Genesis Energy identified how potential environmental effects would be avoided,

remedied, mitigated and ultimately managed. As a means of augmenting the mitigation

measures proposed to address environmental effects set out in the Assessment of

Environmental Effects (AEE), this Environmental Management Plan (EMP) has been prepared to

articulate, and implement those environmental management measures.

This EMP provides an overarching management framework that will manage environmental

effects which arise from the construction, commissioning and operation of the CHWF project. It

identifies roles and responsibilities and includes practical management actions, performance

requirements, and a system of monitoring, reporting and auditing, and corrective action

requirements for the project.

3. Statutory Requirements

Genesis Energy [is seeking/holds] resource consents from Tararua District Council (TDC),

Masterton District Council (MDC), Greater Wellington Regional Council (GWRC) and the

Manawatu-Wanganui Regional Council (MWRC) for the construction, operation, maintenance,

replacement and refurbishment of all structures associated with the CHWF. [These consents

are attached in Appendix B].

The conditions of those consents [sought/held] specify various standards, terms, restrictions

and prohibitions. The purpose of those conditions is to provide certainty in relation to the

effective management and enforceability of the consents, such that in relation to the operation

or development of the CHWF, any adverse effects on the environment are avoided, remedied

or mitigated.

3.1 Consent Timeframes and Implementation

The resource consents Genesis Energy [is seeking/holds] consist of land use consents which

have an unlimited duration and regional resource consents relating to permanent features (for

example bridges and culverts) which have a duration of 35 years. The lapse period or period of

time following the grant of consent where by substantial progress must have been made

towards giving effect to the consent and continues to be made has been [sought/granted] for

10 years. To enable construction of wind farm components, construction related consents have

been [sought/granted] for a period of 20 years.

4. Genesis Energy’s Approach to Environmental Management

Genesis Energy’s approach to environmental management is expressed in a suite of

Environmental Values. Genesis Energy’s intention and principles in relation to its overall

environmental performance are:

We are committed to achieving excellence in all our environmental practices and to ensuring

that environmental and social awareness are the cornerstones of our business. Achieving full

regulatory compliance is considered to be the minimum standard that Genesis Energy must

strive to achieve in the operation of its business3.

At Genesis Energy we:

• Act with integrity at all times

• Foster close relationships with the community and stakeholders, so that their views

can be incorporated into the environmental decision-making processes.

• Acknowledge that our activities affect both the environment and the communities

within which we operate.

• Respect the role of tangata whenua as kaitiaki of the natural resources and taonga

within their rohe.

• Investigate to better understand the nature of the environmental effects – and share

this information with the community and stakeholders.• Seek environmental improvements in all aspects of our business.

Genesis Energy understands that all aspects of its business can impact on the environment and

that in order to reduce that impact it must:

• Identify those who have responsibility for environmental management.

• Identify and document all environmental effects associated with its activities.

• Identify environmental objectives and develop associated work programmes to

address the environmental effects of the activities undertaken.

• Regularly review how well the company environmental values are being

implemented, whether objectives are being met and which areas require corrective

action.

• Report publicly on environmental performance.

3Genesis Energy, Environmental Management Manual, Genesis Energy Environmental Values (GEN-ENV-POL-0006)




6

To achieve these objectives, Genesis Energy operates an Environmental Management System

(EMS) which utilises a number of different business systems to manage the company’s effects

and requirements for environmental management across all Genesis Energy projects and

operational sites. The EMS provides the necessary controls and instructions to achieve the

company’s commitment to environmental excellence and requirement to comply with all

environmental legislation. The EMS applies to all activities involving the use of natural and

physical resources and the environment, from the conceptual stage of any project through to

normal operational activities of Genesis Energy.

5. Environmental Management Framework

The environmental management framework for the CHWF uses the EMP and associated

Supplementary Management Plans (SEMPs) as the primary mechanisms to implement the

measures to manage potential environmental effects. Through the consenting process the EMP,

(in draft form) was prepared and made available to stakeholders and decision makers so that

they could view the objectives of and the proposed approach to environmental management at

the CHWF by Genesis Energy. Specifically the EMP establishes the environmental management

procedures associated with the construction and operation of the CHWF. It sets out Genesis

Energy’s environmental management activities which shall, as a minimum, meet and comply with

consent requirements.

The EMP will be updated to reflect the requirements and conditions imposed by all resource

consents issued for the CHWF project, and updated in response to any future amendments tosuch consents.

5.1 Environmental Management Plan

This EMP has the following objectives:

• To provide for the effective management of the environmental effects and

environmental concerns arising from the CHWF project.

• To ensure the construction of CHWF is compliant with the relevant statutory

requirements (such as conditions of consent).

• To assign management responsibilities and to define reporting requirements.

• To implement the mitigation measures.

• To identify management strategies for implementation.

• To establish a system to assess the effectiveness of environmental management

actions implemented, by way of audits, inspections and monitoring programme set

against acceptable environmental performance criteria.

• To ensure the project contractors, construction and operational staff are aware of

the environmental controls of the project, with the expectation that their activities

will be conducted and managed in accordance with the EMP.

• To regularly review how well the management objectives are being met and that

they remain appropriate.

• To monitor activities and report internally and externally on environmental

performance.

5.2 Supplementary Environmental Management Plans

In addition to the EMP, SEMPs [will be/have been] prepared to ensure a suitable level of

management is implemented for specific locations or activities at the CHWF Site. The processof preparing the SEMPs is outlined below. Contractors involved with the CHWF project will be

contractually obligated to contribute to, and to implement the EMP and the SEMPs. [A

contractor’s ability to comply with the EMP/SEMPs will form part of the construction tender

process].

SEMPs [will be/have been] prepared after the resource consent conditions have been finalised

and [will be/have been] developed in conjunction with the draft EMP with input from the

appointed contractor, relevant specialists, Genesis Energy staff and Council representatives.

Final SEMPs [will/have been] submitted to Council for approval prior to construction

5.3 SEMP Preparation and Requirements

Detailed requirements for each of the SEMPs will be determined and agreed with the

contractor, relevant Genesis Energy staff (e.g. environmental manager, project manager),

technical specialists and the relevant Regional or District Council representatives. This will

involve a review of detailed designs and conditions of consent, Site visits and review of other

information required to determine the extent of effects management required.

Preparation of SEMPs follows the general process described below.

• A preliminary design or methodology is completed.

• A draft SEMP is prepared.

• Councils review the SEMP and provide feedback.

• SEMP finalised and issued to the Councils and contractors.

SEMPs typically include the following. Outline approaches to SEMPs are set out in Appendix F

– Z.

• Objectives and purpose.

• Roles and responsibilities.

• Detailed plans showing location and details of the required management measures.

• Construction or implementation methodology if not provided in the EMP.

• Design criteria.

• Design calculations.

• Any details relating to the operation and maintenance of the proposed management

measures.

• Construction method statements – i.e. method statements for the construction

activities associated with the SEMP.

• Any specific requirements for hazardous substances (such as fuels).

• Actions and measures implemented to minimise environmental effects.




11

• Key contact details.

• Key environmental considerations.

• Construction or implementation programme.

• Monitoring and inspection schedule requirements, frequency and reporting.

• Health and safety requirements and measures.

6. Revisions and EMP Evolution

This section of the EMP establishes the process and approach for documenting changes madeunder the adaptive management approach and also the protocol for managing design

finalisation. The adaptive management approach involves regular monitoring and reporting which

creates a continuous improvement feedback loop and ensures that actual On-site effects are

being addressed and managed appropriately.

Genesis Energy will operate a “plan-do-check-act” adaptive management approach. The

approach enables objectives to be set, actions to be monitored and performance to be

evaluated against those objectives and for this to be communicated to relevant stakeholders. It

will enable reviews of progress to check the effectiveness of actions and to ensure that

improvements are implemented accordingly.

6.1 EMP Evolution and Control

The EMP is subject to revision based on review, experience and changes in technology, thereby

taking an adaptive approach to improve future management. The key mechanisms for this

include the following:

• Review of measures utilised to manage effects.

• Improvements identified from any incident response.

• Consultation with relevant stakeholders.

• Undertaking an annual review.

To maintain control over any changes in approach made through the evolution of the EMP, this

EMP has been issued as a controlled document. Any other copies issued in part or full are

deemed not to be controlled copies and will not be updated nor may they be considered a

current document. All copies shall be distributed in accordance to the document register. On

receipt of a revision the copyholder shall discard the superseded copy and adopt the new copy.

6.2 Component Location Consenting Approach

Overall, the environmental effects assessment for the CHWF Project has been undertaken on a

comprehensive, conservative and robust basis.

The AEE, and the supporting technical information, [is/was] provided in such detail as

corresponds with the scale and significance of the effects that the CHWF activities may have on

the environment. As noted, the CHWF Site encompasses some 30,000 ha, with a construction

footprint of 861 ha and an operational footprint of some 226 ha. In order to provide an

assessment of all potential environmental effects (positive and negative), independent experts




13

[have undertaken/undertook] both specific and representative effects assessments. Thus, while

not every spatial area of the 30,000 ha Site [has been/was] specifically assessed, the worst

case position for all potential effects [has been/was] assessed regardless of the final location of

all the activities for which resource consent has been [sought/granted].

Optimisation of the CHWF design [is/was] proposed to make the best use of the wind resource

while responding to technological advances, opportunities to minimise environmental effects

and in order to take account of Site conditions following grant of resource consent. When

implementing the CHWF project, Genesis Energy will ensure that final designs fit within the

overall location and extent of effects described in the AEE and authorised by the resource

consents [sought/granted] . It will ensure that the nature and scale of the effects associated with

the final design are no greater than the authorised adverse effects.

In that regard, it is anticipated that the following protocol will form part of the conditions of

consent.

6.2.1 Protocol for Managing Design Finalisation

During the development of the final design, the following protocol will apply:

1. Confirm the final location of the CHWF components.

2. Document the reasons why the final location has been selected.

3. Prepare detailed design drawings.

4. Ensure that exclusion areas where infrastructure shall not be located contain noinfrastructure elements apart from those specific locations sought in the AEE.

5. Undertake a confirmatory process to ensure environmental effects are no greater thanthat contained in the AEE.

6. Report the findings of the confirmatory process, to confirm that for the project as awhole:

a. Areas of legally protected habitats (DOC, QEII) and, ‘rare’, ‘threatened’ or‘at risk’ habitats identified under statutory plans will not be disturbed.

b. Areas of ‘high ecological value’ as defined in the Ecological Effects Assessment in support of the AEE will be avoided, except to the extentalready outlined in the CHWF Project Figures shown in the AEE. Clearanceof a limited amount of ‘high ecological value’ vegetation is described andthis quantity will not be exceeded in construction of the CHWF.

c. Clearance of indigenous vegetation will be minimised and will not cause themaximum quantity of indigenous vegetation clearance of 66 ha described inthe AEE to be exceeded.

d. Watercourse crossings will not vary in location by more than 100m each




14

side of locations identified in the AEE.

e. Gullies with watercourses will be avoided unless it can be demonstratedthat downstream water quality effects are no more than minor.

f. Seepage areas dominated by indigenous species with an area greater than0.05ha will be avoided.

g. Total CHWF earthworks volumes described in the AEE are not exceeded.

h. Noise standards will be complied with or effects will be appropriatelymitigated.

Overall, the design of the CHWF has been undertaken to a level sufficient to enable the

environmental effects to be assessed robustly and conservatively. During detailed design and

optimisation, the protocol set out above will ensure that effects are well managed and will not

exceed the nature and scale of effects as described in the AEE.

Table 3, below, summarises the parameters within which Genesis Energy will refine and finalise

the location of the CHWF infrastructure.

Component Rationale Location Description

Turbines

(including

TurbineFoundationsand TurbinePlatforms)

Siting refinement is important to allow for variation in spacing between Turbines to

maximise energy output. Spacing variesdepending on the size of the Turbine rotor andtherefore, optimal spacing can only bedetermined once the final turbine model(s) areselected after resource consent acquisition.Four Indicative Turbine Layouts have beenestablished to provide a basis for representativeengineering and environmental assessments andto illustrate how different Turbine sizes may beplaced within the Turbine Corridor.

Turbines may not be sited anywhereother than in the Turbine Corridor.

TurbineCorridor

The Turbine Corridor incorporates all areaswithin the CHWF Site identified for turbine

placement. The development and refinement ofthe Turbine Corridor has incorporatedrepresentative environmental and engineeringassessments to avoid, remedy or mitigateadverse environmental effects.

The area and location of the TurbineCorridor is located where indicated

in the CHWF Project Maps.

InternalRoads

(includingLay-bys)

Internal Roads have been designed andassociated earthworks volumes calculated andwill generally be located where indicated.However the scope sought within the resourceconsent will enable the final location of theInternal Roads to be confirmed during thedetailed design phase. Further refinement may

be required due to the following:

Technological advances in transporters or

Internal Roads are likely to belocated where indicated in theCHWF Project Maps but may belocated anywhere within the Site,subject to the limits presentedbelow:

Unforeseen ground conditions or environmentalconstraints.

Unidentified archaeological sites or features.

The Internal Road design approach is consideredappropriate at this Site because of the largeproportion of the Site consisting of low ornegligible ecological value. The location of theInternal Roads will be influenced by the fixedlocations of key CHWF infrastructure (Turbines

within the Turbine Corridor and Substations) towhich they will provide access.

(2) Areas of ‘high ecological value’as defined in the Ecological Effects Assessment in support of the AEEwill be avoided, except to the extentalready outlined in the CHWFProject Figures and shown in the AEE. Clearance of a limited amountof ‘high ecological value’ vegetationis described and this quantity willnot be exceeded in construction ofthe CHWF.

(3) Clearance of indigenous

vegetation will be minimised and willnot cause the maximum quantity ofindigenous vegetation clearance of66 ha described in the AEE to beexceeded.

(4) Watercourse crossings will not vary in location by more than 100meach side of locations identified inthe CHWF Project Figures.

(5) Gullies with watercourses will beavoided unless it can be

demonstrated that downstreamwater quality effects are no morethan minor.

(6) Seepage areas dominated byindigenous species with an areagreater than 0.05ha will be avoided.

(7) Total CHWF earthworks volumesdescribed in the AEE are notexceeded.

MainSubstation

Two locations have been identified for the MainSubstation. The key factors that will determine

which location will be most appropriate will bethe final size, location and order of stages ofconstruction, and the final location of theExternal Transmission Line.

Two alternative locations also provideredundancy in the unlikely event that onelocation is found to be unsuitable during detaileddesign.

The Main Substation will be locatedat one of the two locations shown in

the CHWF Project Maps.

SatelliteSubstation

The Switching Station location was identified

after a thorough assessment of the overall Siteagainst a range of suitability criteria, such asarea, topography, visibility, proximity todwellings, potential for flood risk, accessibility,expected proximity to the External TransmissionLine connection point and ecology.

The location of the Switching

Station is shown in the CHWFProject Maps.

InternalTransmission Line

The Internal Transmission Line has beendesigned to a reasonably high level of certaintyand apart from micro-siting of towers is notexpected to change.

The location indicated in the AEE shows some

alternative arrangements depending on thelocation of the Main Substation and whether theSwitching Station is utilised.

The location of the InternalTransmission Line will be within 50mof the location indicated in theCHWF Project Maps.

The location of the Internal

Transmission towers will be within50m of the locations indicated in theCHWF Project Maps and will bepositioned to avoid clearance ortrimming of indigenous vegetation tothe extent practicable.

33kVoverheadlines andundergroundcables

Wherever practical, the 33kV reticulationsystem will follow Internal Roads so therequirement for variation from the routesindicated will match that of the Internal Roads.

The opportunity arising from refinement, and thedegree of constraint applied is as for the InternalRoads.

Other EBoP Other EBoP components such as switchgearhuts will generally be located near previouslylisted EBoP components (substations, overheadlines and underground cables) and will vary intheir location as these other components do.

Excess Fill Areas

On-site Excess Fill Areas have been identified assuitable from both an engineering andenvironmental perspective. They are locatednear or adjacent to Internal Roads to minimisetransport of Excess Fill and so may vary in

location if Internal Roads relocations arerequired. Other variations may be required toachieve engineering or environmentalimprovements and additional Excess Fill Areasmay also be identified by the contractor.

CentralLaydown Areas

Indicative Central Laydown Area locations havebeen identified to indicate suitable sites anddemonstrate that the requirement to provideCentral Laydown Areas can be achieved.

ContractorCompounds

The contractor will identify a suitable location forthe Contractor Compound prior to construction.

Operationsand

The location of O&M facilities will be determinedprior to construction depending on the final size,

These components are likely to belocated where indicated in theCHWF Project Maps but may belocated anywhere within the Site,subject to the following limitations:

(1) Areas of legally protectedhabitats (DOC, QEII) and, ‘rare’,‘threatened’ or ‘at risk’ habitatsidentified under statutory plans willnot be disturbed.

(2) Areas of ‘high ecological value’as defined in the Ecological Effects Assessment in support of the AEEwill be avoided, except to theextent already outlined in theCHWF Project Figures and shownin the AEE. Clearance of a limitedamount ‘high ecological value’ vegetation is described and thisquantity will not be exceeded inconstruction of the CHWF.

(3) Clearance of indigenous vegetation will be minimised and willnot cause the maximum quantity ofindigenous vegetation clearance of66 ha described in the AEE to beexceeded.

(4) Gullies with watercourses willbe avoided unless it can be

demonstrated that downstreamwater quality effects are no more

Quarries Quarries will be established at the locationsindicated or additional sites if identified duringconstruction.

CrushingPlant

Crushing plant is likely to be located at or nearthe quarry sites.

ConcreteBatchingPlants

Concrete Batching Plants will be located eithernear current construction sites, or near materialsources such as quarries or water abstractionsites. Indicative locations have been identifiedwith specific locations to be determined prior toconstruction. The plants will be re-locatable, with

only one or two locations operating concurrentlyat any one time and sites being rehabilitated assoon as the Concrete Batching Plant isrelocated.

8. Construction Environmental Management

This section of the EMP outlines the proposed general environmental management measures to

be implemented to address environmental effects. Detailed methods for specific sites and

issues will be identified within the SEMPs, provided in appendix to the EMP.

8.1 General Operations

Works will not commence On-site until the following actions have been undertaken:

• Pre construction conditions of resource consent have been met and authorised by

Council.

• All other approvals required from Council have been received for a given project

area.

• Relevant EMPs and SEMPs are have been approved by the relevant authority.

8.2 Provision of Information, Training and Inductions

All organisations and individuals working on the CHWF project will be required to complete a

formal Site induction prior to commencing work On-site. The induction will include importantenvironmental issues pertaining to the Site including environmental management requirements,

accidental discovery of cultural or archaeological sites or material, emergency response

procedures and incident reporting, as well as Health and Safety information and requirements.

Attendees will be provided with a copy of the EMP and any appropriate SEMP to read prior to

commencing work On-site. A register will be maintained by the contractor’s Project Manager

which needs to be signed prior to an individual commencing work On-site confirming they have

understood the contents of the EMP and relevant SEMPs.

Should any specialised environmental training be identified as being necessary for personnel at

the Site, training will be provided by a suitably qualified person. A record of the training will bekept by the contractor’s Project Manager.

Environmental issues and management will be included as an item on the agenda of daily

toolbox meetings to assist in the continuing development and improved performance of

environmental management On-site.

9. Erosion and Sediment Control Measures

Exposure of soil during the construction process and the formation of topsoil and weatheredrock stockpiles, means that there is potential for an increase in erosion and sediment

discharges, including airborne dust. Accordingly, erosion and sediment control measures

will form integral components of the construction process for the CHWF, with appropriate

planning and adoption of control measures for all earthworks to minimise the effect on the

receiving environment.

The minimisation of erosion is the most effective way of reducing sediment discharges.

Earthworks activities associated with the construction process will be kept to the minimum

area necessary, and exposed surfaces will be stabilised until the Site is appropriately

revegetated.

The following general objectives underpin erosion control at the CHWF:

• Minimising the area disturbed by construction activities.

• Progressively completing construction activities on a stage-by-stage basis.

• Revegetating and rehabilitating areas disturbed as soon as possible after

earthworks have been completed.

• Stabilising material storage areas for future use.

In addition, the potential effects associated with earthworks activities can be prevented and

minimised with the following guiding principles:

• Maintain separation of earthworks from watercourses.

• Divert clean surface runoff away from areas of earthworks or soil stockpiles.

• Reduce the energy of surface flows in areas of potential erosion.

• Allow for the passage of extreme flows and protect against blockage of

infrastructure.

• Provide containment for sediment entrained in surface flows.

• Treat sediment laden water leaving the construction site.

• Promptly stabilise or revegetate disturbed areas.

• Monitoring to ensure erosion and sediment controls are operating effectively.

A range of erosion and sediment control measures will be implemented as part of the

construction process associated with CHWF. These measures will be contained within

relevant ESCPs and are summarised below. The ESCPs will set out measures to avoid and

minimise potential impacts of construction works on soils and waterways at the Site, and

will be prepared for each phase of development and submitted to Council prior to

construction.




32

A draft example of an ESCP identifying the purpose, objectives and content of the ESCP(s)

is provided in Appendix F.

9.1 Erosion Control Measures

A summary of erosion control measures are set out below. These will be implemented in

combination with sediment control measures set out in section 9.2.

9.1.1 Clean Water Diversion Bund

A clean water diversion bund is used to divert clean surface flows away from unstabilised

soils. Bunds are set up around the uphill perimeter of the active works area, constructed of

compacted earth and then stabilised. Existing turf from the active works area should beused to line the constructed bund where appropriate.

9.1.2 Contour Drains

Contour drains consist of a temporary bund or channel cut across the face of the active

works area to collect runoff and provide a low velocity pathway to either a sediment control

device or a collector drain. Contour drains should be installed at the end of every day, or

when the site is about to be shut down due to impending inclement weather.

9.1.3 Collector Drains

Collector drains consist of a channel cut into the active works area to collect flow from

contour drains and discharge the flow into a sediment control device. These cut channels

are a semi permanent feature, so they must be located along a suitable path. Check dams

and reinforcement may be required under certain circumstances.

9.1.4 Rock Check Dams

Rock dams are placed across steep clean water diversions or collector drains to slow the

water velocity where it exceeds the erosive limit of the soil.

9.1.5 Channel Reinforcement

Channel reinforcement consists of lining clean water diversions or collector drains with

rock, geotextile, or other reinforcement material.

9.1.6 Benched Slopes

Benched slopes involve a reverse slope bench cut into steep and high batters to prevent

stormwater concentrating into erosive rills. Reverse benches are expected to require a

drop pipe to convey the runoff down the subsequent cut slopes.




33

9.1.7 Drop Pipes

Drop pipes are temporary structures used to convey runoff from a channel or other type of

collection point down a steep slope without requiring an overland flow. The entrance to thepipe is flared and constructed of compacted earth reinforced with geotextile.

9.1.8 Flow Dispersal Outlets

Flow dispersal outlets are connected to a section of drainage coil or pipe that has had slots

cut into it fixed perpendicular to the slope in order to promote broad sheet flow rather than

a concentrated flow. This is suitable where flow is being discharged away from a

watercourse. The dispersal device must be laid flat and perpendicular to slope so that flow

will exit from the full length of pipe rather than concentrated at one point.

9.1.9 Rip-rap reinforced Outlets

A basin, wingwall, or other suitable structure based on existing relief to prevent scour and

erosion at and around outlets. This is suitable where flow is being discharged to a

watercourse. Depending on the situation, armouring of the opposite side and/or

downstream channel of the stream bank may also be required.

9.1.10 Stream Flow Diversion

A stream flow diversion diverts perennial water flows around a works area that is located in

a watercourse.

9.2 Sediment Control

In combination with the erosion control measures set out above, a suite of sediment control

measures are proposed for the CHWF Site. A summary of sediment control measures are

set out below.

9.2.1 Silt Fences

Silt fences are a barrier device comprising a geotextile fence used to intercept sediment

laden runoff from areas that are either unable to drain to, or are of a size that does not

warrant a communal sediment control device. Silt fences will be installed on a contour and

service catchment area’s below 0.5 ha as required.

9.2.2 Super Silt Fences

Super silt fences are the same as for silt fences but include chain link and tensioned wire for

reinforcement of the geotextile. The fence is reinforced with chain link at 400mm and

800mm above ground, comprising a double layer of geotextile from 400mm above ground




34

to 200mm below ground. Super silt fences will be used to service catchments larger than

0.5ha where no other sediment control method is suitable.

9.2.3 Sediment Control Ponds

Sediment control ponds are a temporary pond with storage volume and outlet structure

designed to provide sufficient settling time for sediment to settle out for a range of events

up to the design storm. Ponds require maintenance by way of excavation when 20% of

total volume is lost to accumulated sediments. A level spreader will be used between the

forebay and the pond to ensure infows do not cause sediment re-suspension. Pond

catchments should generally be limited to less than 3 ha in area.

9.2.4 Sediment Control Ponds with Flocculation

Same as for sediment control ponds, but include a flocculation dosing system to aid the

settlement of suspended solids. Bench scale tests will be undertaken to determine the

suitability of flocculation systems, and if suitable, appropriate dosing rates. Dosing systems

include batch dosing, rainfall activated liquid dosing, and flow activated dosing.

Flocculants can be toxic to fauna, so stringent care will be taken to establish and operate

correct dosing regimes that ensure residual levels are safe in the environment. Flocculation

pond catchments should generally be limited to an area less than 5 ha.

9.2.5 Decanting Earth Bunds

A Decanting Earth Bund is a compacted earth bund established to created an impoundmentarea where runoff can pond and allow sediment to settle out. This is similar to a sediment

control pond but with a different outlet type and without a forebay. Catchments should

generally be limited to less than 0.3 ha and bunds will be excavated when 20% of total

volume lost to accumulated sediments.

9.2.6 Improved Decanting Earth Bund

Same as Decanting Earth Bund but with improved inlet and outlet systems as used by

sediment control ponds. A level spreader will be used at the inlet to the bund to ensure

inflows do not cause sediment re-suspension. Improved bund catchments will be limited toless than 1.5 ha and bunds should be excavated when 20% of total volume lost to

accumulated sediments.

9.2.7 Wheel Wash Stations

A wheel wash station is a flooded basin lined with agitators to remove sediments

accumulated on the wheels of trucks prior to them exiting the Site. Daily flushing of basins

will occur, with effluent being discharged into a sediment control device and any

contaminants treated in an appropriate manner. Generally wheel wash stations will be at the

Site exits onto a sealed road, and often used in conjunction with a stabilised entrance.




35

9.3 Stabilisation or Surface Treatment Methods

Stabilisation and surface treatment methods will utilised at the CHWF. The use of these

measures will be refined based on site specific requirements and On-site experience. A list

of those methods that will be considered for use in the appropriate circumstances at the

CHWF is set out below.

9.3.1 Surface Roughening

Surface Roughening consists of track rolling to roughen a bare surface to slow the velocity

of sheet flow, prevent runoff concentrating into erosive rills, and aid the establishment of

vegetative cover.

9.3.2 Stabilised Construction Entrance

A stabilised construction entrance is a stabilised pad of aggregate or asphalted to prevent

erosion at a highly trafficked area, and to provide an opportunity for dust accumulated on

the truck scrape to be vibrated off. The drainage from stabilised entrances will discharge to

a sediment control device and contaminants treated in an appropriate manner.

9.3.3 Staging Works and Progressive Stabilisation

Staging or sequencing of construction and progressive stabilization and rehabilitation is a

function of construction planning. Staging requires work areas to be segmented intoseparate task areas that can be opened and then completed prior to moving onto

successive areas. These completed areas will be stabilised as they were finished, resulting

in the Site being progressively opened and then stabilised. This ensures that the minimum

area of soils are exposed at any one time and also allows for high risk work to be planned

over summer while lower risk work can be scheduled for winter works.

9.3.4 Top Soiling and Grass Sowing

Spreading topsoil and sowing grass seed to permanently stabilise exposed areas will

receive a minimum thickness of 100 mm topsoil (depending on available supply at the Site).

9.3.5 Mulching

Mulching involves spreading straw or other suitable materials to protect exposed surfaces

from erosion and to promote establishment of vegetative cover. A sufficient quantity of

mulch needs to be applied to form a protective layer over the exposed surface. Mulching

will be used as temporary measure at the Site or will be used in conjunction with top soiling

and grass sowing for permanent stabilisation.




36

9.3.6 Geotextile

Geotextiles (woven or other artificial but non-degradable geotextile) will be used for the

protection of exposed areas. The type, thickness, strength and hydraulic performance of thegeotextile used depend on the situation and purpose of use. Common uses include lining

steep channels, providing removable stabilisation overnight or during inclement weather,

and lining excavations prior to placement of riprap or aggregate.

9.3.7 Biodegradable Fibre Matting

Biodegradable Fibre Matting is used to protect exposed areas and to promote

establishment of vegetative cover, often to stabilise topsoil and grass sown on steeper

slopes.

9.3.8 Hydroseeding

Hydroseeding activities will apply a mixture of grass seed, fertiliser and a binding agent

(usually wood or paper pulp) sprayed onto steep or otherwise critical exposed areas.

9.3.9 Tackifier enhanced Mulching or Hydroseeding

Tackifiers are polymers which are added to hydroseeding pulp to improve immediate

erosion protection and to aid adhesion to exposed surfaces. These tackifiers are often also

used as flocculants in sediment control ponds. Any restriction on the use of tackifiers will be

considered before application.

9.3.10 Spray Concrete

Spray concrete is a high cement content grout which is applied to immediately stabilise and

reinforce steep slopes and other critical areas. This will be used to stabilise loose rock on

steep batters adjacent to roads and bridge abutments.

9.4 Maintenance of Erosion and Sediment Control Measures

Ongoing maintenance of erosion and sediment control structures is necessary to ensure

that they remain fit for purpose and functional in a wet weather event. Such devices will be

inspected as part of the supervision duties undertaken by responsible parties and

maintained in working order whilst they are required. Inspections shall occur prior to, during

and after prolonged periods of heavy rain, as appropriate. Any defects will be promptly

rectified.

Intensive monitoring and maintenance will be required to optimise and maintain erosion and

sediment controls during construction. This will include:

• Maintaining access to ponds and decanting earth bunds following wet weather;




37

• Cleaning out ponds and decanting earth bunds following heavy rainfall and high

sediment load events;

• Signposting ponds and decanting earth bunds to identify them;

• Maintaining open communications and cooperation with Council appointed

compliance staff;

• Maintaining electronic records of device condition (including photos and

inspection records);

• Providing as built drawings of key ponds and decanting earth bunds and their

catchment areas; and

• Monitoring occurrences of and managing stock interference with erosion and

sediment control measures.

In addition to specific measures, topsoil that is to be used in revegetation will be stockpiled

away from drainage lines and watercourses. These areas will be managed to minimise

erosion with surface stabilisation to prevent wind erosion.

9.5 Removal of Erosion and Sediment Control Measures

Erosion and sediment control measures will be monitored and maintained as set out in the

EMP and ESCP(s). When the use of control measures is determined to no longer be

necessary (construction activities are completed and reinstatement and revegetation of thedisturbed area implemented), Council will be advised that the area has been adequately

stabilised and that risks from erosion are low.

For clarity, removal shall only be considered when the area in question is inherently resistant

to erosion or rendered resistant. In terms of revegetation by way of grassing or

hydroseeding, inherent resistance is determined to be when ground cover is in excess of

80%.




38

10. Water Management

General drainage works may be required across the Site to manage any seepages duringthe earthworks activities. Surface discharges from seepages and any springs that are

covered by construction earthworks (e.g. Excess Fill Areas) will be diverted beneath the fill

to discharge at a suitable downslope location. This will be achieved by installing under-

drainage beneath the fill areas where appropriate

Open excavations (for example Turbine Foundations) may collect either ground or rain

water. If this occurs, the excavation will be dewatered, most likely by pumping. Discharges

generated by this will be treated in accordance with the ESCP(s) and Drainage Management

Plan (DMP).

Some Internal Roads, Central Laydown Areas, turbines, Excess Fill Sites or other site

elements have been sited over an existing On-site pond. Where this occurs the ponds are

usually relatively small locally constructed retention areas used by farmers and do not hold

large volumes of water, or similarly small natural depressions where water has been allowed

to accumulate. If required, ponds will be de-watered in a controlled manner and if

appropriate, treated in accordance with the ESCP and DMP. It is not expected that this

practice will be necessary at many sites.

In addition to the ESCP (Appendix F), a draft example of the DMP is also provided in

Appendix K. This sets out the purpose, objectives and content for the DMP.

10.1 Quarry Water Management

It is estimated that 0.24 m3 of water will be required for each 1m3 of gravel in the crushing

process. Once the gravel aggregate has been sorted it will be transported to the Concrete

Batching Plant for concrete production or it will be stockpiled for use in road formation.

Detailed water management measures for quarries and aggregate processing will be

established and set out in detail in Quarry Management Plan (QMP) located in Appendix H.

Typical arrangements will include:

• Quarries will be surrounded by a cut-off nib or bund, and will drain to a multi

stage settling pond.

• Recycled water will be drawn off from this.

• Excess clean water will discharge in a controlled manner onto grass slopes.

• Sludge in settlement ponds is likely to contain a very low level of contaminants.

This will be tested during construction in accordance with the agreed monitoring

approach. Un-contaminated sludge (essentially silt and clay) will be included in

Excess Fill Areas.




39

• Any contaminated sludge will be removed off site to a landfill.

10.2 Concrete Batching Water Management

General water management measures for concrete batching plants will include:

• Full management of sediment and erosion potential in accordance with the

ESCP.

• Isolation and capture of runoff from activity areas (cement silo, concrete

batching, load-out, wash-pits, sludge drying and waste concrete) into settling

ponds for recycling.

• Water will be recycled for concrete manufacture and washing the inside of the

truck bowls when it is available.

• Where storage for flows from within the activity area is full, treatment is

provided.

• Stormwater from non activity areas will be collected and treated prior to

discharge.

An outline Concrete Batching Plant Management Plan (CBMP) is provided in Appendix I.

10.3 Water Quality Monitoring

Water quality will be managed through a monitoring plan comprising a Baseline Aquatic

Monitoring Plan (BAMP) which will establish a baseline of receiving water quality at

reference sites prior to construction both during dry periods and in response to rainfall

events. A Construction Aquatic Monitoring Plan (CAMP) will also be used to establish

water quality at reference sites during construction and monitor water discharged from

representative sediment control ponds. This will enable the performance of management

measures against environmental and operational objectives to be evaluated. Detailed

information will be set out in the BAMP (Appendix J) and CAMP (Appendix K).

10.4 Wastewater Management

Toilet facilities will be provided On-site, with holding tanks or septic tanks utilised. Sewerage

will be removed from Site and disposed of at a registered waste treatment facility. Wastes

generated from wash-down activities will be collected and disposed of appropriately.




40

11. Site Rehabilitation and Reinstatement

11.1 Overview

The construction of the CHWF will be progressive in nature and post construction

reinstatement of all disturbed areas will also occur in a progressive manner, and in

accordance with the measures proposed within this EMP and relevant SEMPs. This

sequential reinstatement process will occur from upstream areas moving through to

downstream areas. The reinstatement process will ensure that all areas, including any

earthworks batters, internal roads, channels and sedimentation ponds are appropriately

stabilised before the Contractor demobilises from that particular area within the Site.

Reinstatement and revegetation will focus on providing a stable landform and vegetativecover promptly after the infrastructure is no longer required, or when the earthworks activity

is complete. Once construction activity is completed in a particular cluster or area, the

following activities shall be undertaken:

• All building and construction materials shall be removed from the Site and

disposed at a licensed facility.

• Temporary facilities such as contractor compounds, concrete batching plants

and erosion and sediment controls shall be removed from Site

•

Reinstatement will involve the stabilisation and rehabilitation of disturbed areasby ripping, top soiling, and revegetating the area.

• Follow up maintenance will be undertaken until the area is satisfactorily

stabilised and restored.

• The appropriate Council shall be notified.

Retention of topsoil for use in rehabilitation will form an integral component of the

rehabilitation process. In all areas of excavation, topsoil will be removed and stockpiled for

later use in the rehabilitation and revegetation of disturbed areas.

11.2 Revegetation

The objective of revegetation and rehabilitation will (apart from where there are non-

vegetated solutions proposed) be to replace vegetation as like-for-like. To assist vegetation

establishment, stock will be excluded from recently established grass and indigenous

plantings, with measures for control of pest animals and weeds undertaken to improve

establishment success. The control of pest animals and weeds will be provided for within

the Revegetation Plan (Appendix L) and within other relevant Biodiversity Management

SEMPs such as the Weed Hygiene and Surveillance Plan (Appendix M). A combination ofmethods may be utilised and are identified within this section.




41

11.2.1 Hydroseeding

Hydroseeding will comprise the application of a mixture of grass seed, fertiliser and a

binding agent (usually wood or paper pulp) sprayed onto steep or otherwise critical exposedareas. Surface roughening exposed areas will aid vegetation establishment in hydroseeded

areas. Because hydroseeding does not retain moisture as well as topsoil, grass seed and

mulching, the timing of spraying important.

The benefits of hydroseeding are that it offers a solution to revegetate difficult terrain which

cannot be established by using normal methods. It is anticipated that the seed mix to be

used in hydroseeding will include perennial ryegrass, brown top and clover. The seed mix

must be free of weed seeds and will take account of the preferences and recommendations

of CHWF landowners.

Due to the steepness of the areas proposed for hydroseeding, Genesis Energy will require

that a uniform hydroseeded cover is provided. Areas being hydroseeded shall be inspected

six to eight weeks after the application and any areas that have failed to establish shall be

retreated until in excess of 80% cover is achieved and the area is deemed to be inherently

resistant to erosion

11.2.2 Direct Drilling

Direct drilling is a method of establishing pasture cover over large areas where suitable

contour allows for machinery to manoeuvre. In areas that are to be direct drilled, preparation

may include light cultivation and rolling to assist in pasture establishment. In areas capableof being direct drilled, the expectation is that the area can be fully reestablished into pasture

cover (100% cover). Depending on the prevailing climatic conditions, the normal timeframes

to observe successful establishment of vegetative cover is approximately six weeks. All

areas will be reviewed six to eight weeks after direct drilling to determine the overall

success of the established pasture and to enable resowing to occur in areas which have not

successfully established. A range of species will be used for revegetating the Site, with

pasture grasses including perennial ryegrass, brown top and clover where appropriate.

11.2.3 Fascining

Fascining involves the laying of seed-bearing slash or mulch branches with viable seed that

has been harvested from plants and placed across the slope to retain sediment. Often this

needs to be held in place with stakes or biodegradable netting. Seed contained on the

material germinates under the protective leaf mulch and establishes. The species likely to

be used for fascining activities at the CHWF Site are manuka and kanuka. Seasonal

considerations are necessary to ensure foliage collected contains viable seed.




42

11.2.4 Direct Planting

Direct planting will use plants that are naturally found in the project area and are suited to

the Site. In order to reinstate or provide establishment phase indigenous vegetation cover,species such as kanuka, toetoe, manuka, karamu, ti kouka, piripiri and coprosma will be

used initially. Secondary phase indigenous species will be planted (known as enrichment) in

the appropriate areas once the initial canopy cover has been established. Slow release

fertiliser and water crystals will be used where necessary to assist vegetation

establishment. The areas proposed to be revegetated will be determined and set out in the

relevant SEMP, with appropriate species, the composition of the planting mix, plant spacing,

plant sizes and maintenance requirements.

11.2.5 Natural Revegatation

Natural Revegetation relies on the existing seed bank within soils and surrounding

vegetation to naturally establish or colonise areas. Natural revegetation of areas can be

enhanced when topsoil is collected from an area with a significant seed bank and spread to

an area identified for revegetation (e.g. not stockpiled).

11.2.6 Maintenance of Revegetated Areas

Ongoing maintenance in the form of pest and weed control, replacement of vegetation

which has failed to establish, and fencing will be determined for specific sites and set out in

the relevant SEMP.

Secure fencing or alternative protection will be necessary to prevent vegetation being eaten

by stock and to allow native plants to grow and or regenerate. Options for control of goats

and deer are being considered as part of a wider control effort within the CHWF properties;

however pests such as possums, hares and rabbits can cause considerable damage to

establishing vegetation and will require more focused control until vegetation has

established.

Weed control will also be undertaken in order to reduce competition from weeds for the

first 3 years following planting / sowing. Weeds will be suppressed by use of an appropriate

mulch or herbicide.

11.2.7 Stock Access and Farm Management

Construction activities will at times conflict with normal farm and stock management

operations within the CHWF, expecting the need to remove fencing and other containment

measures in order to undertake earthworks.

These aspects of the project will be managed in consultation with individual farm managers

and CHWF Landowners. In order to provide for stock containment, stock will be moved to

secure paddocks and fencing will be reinstated as soon as practicable.




43

12. Air Quality

Various activities associated with the construction of the CHWF are expected to result inthe creation and discharge of dust into the air. The effects are expected to be less than

minor; however management measures will be employed as necessary. Management of the

effects caused by dust discharges will be covered in the ESCP(s).

12.1 Dust Control

To manage dust emissions from the CHWF Site during construction the following measures

will be implemented as appropriate:

• Temporary sealing of roads at key areas.

• Full compliance with the EMP and ESCP (Appendix F) and other relevant

management plans

• Temporary water application to suppress dust in certain areas or conditions

• Use of cement silos and aggregate bins to avoid aeolian dust.

• Provision of wheel washing facilities (where appropriate)

• Hydroseeding and other revegetation techniques will be applied to earthworks

sites as quickly as possible post excavation.

• Earthworks sites will be limited to areas of immediate construction.

• Restriction of traffic speeds.

• Vehicle tailgates will be properly sealed.

In addition, all stockpiles will be covered or stabilised to avoid loss of material during high

wind events and where practicable, placed in areas sheltered from the wind. Where a

significant amount of material is lost, a review of storage procedures will be undertaken to

avoid reoccurrence of the event.

12.2 Machinery and Vehicle Condition

Vehicles and machinery are one possible source of air contamination. All construction

machinery and vehicles operating on the CHWF Site will be in a good state of repair and be

well maintained throughout the project.




44

13. Construction Noise Management

The assessment of construction noise for the CHWF elements identified that theconstruction of the CHWF would readily comply with New Zealand Standard 6803:1999 –

Acoustics -Construction Noise. It was noted that during construction of roads, and in the

operation of construction vehicles over these roads there is potential to produce noise

levels which approach the limits of acceptability for construction noise. In order to ensure

compliance within the noise limits, and to address noise issues which may arise upon

commencement of construction a Construction Noise Management Plan (CNMP) shall be

prepared and implemented. The CNMP describes the manner in which noise effects will be

controlled to comply with the construction noise standard (except where appropriate forms

of mitigation have been provided), and to minimise noise effects on residents and other

noise sensitive activities near the Site. This CNMP includes a procedure for responding to

noise complaints. An outline CNMP is located in Appendix N.

13.1 Controlled Blasting

It is anticipated that the excavation work will be able to be undertaken entirely using

excavators and dozers with ripping attachments. However, it is possible that harder material

is encountered and that it may be necessary to undertake controlled blasting operations to

assist excavation activities.

Controlled blasting involves the breaking up of larger rock into smaller, more manageable

pieces. Rock drilling to plant the explosives is undertaken.

Any requirement for controlled blasting will be documented formally by the contractor in a

request to the Project Manager and Project Environmental Manager (or others as

necessary). The request will contain the following information:

• Name and qualifications of the responsible person(s)

• Current Approved Handlers Certification of the responsible person(s)

• Location of the area proposed for the discharge of the explosives

• Information on the method and explosive to be used and the depth and spacing

of the charges.

• The procedure for site clearance and post blast reoccupation

• Storage and handling of explosives.

• Occupational health and safety requirements

• Noise monitoring requirements.




45

14. Traffic and Transport Management

A Construction Traffic Management Plan (CTMP) is proposed to manage all constructiontraffic associated with the development of the CHWF.

In advance of the CTMP being prepared, a Construction Traffic Management Framework

(CTMF) has been prepared and is provided as Appendix O. This CTMF establishes the

purpose, objectives, and process for development of the CTMP. It specifies the minimum

content for the CTMP and the deliverable expectations to be met. The consultative and

approval requirements for the plan provide an assurance about the management, control

and delivery of the proposal.




46

15. Concrete Batching Plant Management

Up to four Concrete Batching Plant locations have been proposed On-site for the CHWFproject. The plants would be re-locatable with one or two locations concurrently operational

at any one time. Concrete Batching Plants may also be located next to water sources Off-

site.

A Concrete Batching Plant will consist of a concrete mixer, cement bins, sand and

aggregate stockpiles, water storage tanks and storage areas for equipment and tools.

Sufficient area is required for the use of front end loaders, delivery of materials and entry

and exit of agitator trucks. The Concrete Batching Plants will be approximately 5,600 m2 in

size.

Environmental management measures for the Concrete Batching Plant will be agreed in a

specific Concrete Batching Plant Management Plan (CBMP) (see Appendix I).




47

16. Management of Quarries and Crushing Facilities

Potential gravel sources for concrete production and for construction of roads and otherhardstanding areas have been identified both On-site and Off-site. In order to use the

gravel, it will need to be quarried or excavated from the gravel source site.

An indicative quarry layout can be found in the Quarry Management Plan (QMP) located in

Appendix H.

The typical process for quarrying materials is as follows:

• Erosion and sediment controls will be established in accordance with the ESCP

and QMP.• Topsoil will be removed and stockpiled for use in rehabilitation,

• Overburden will be removed to On-site Excess Fill Areas

• Gravel resources will be excavated using earthmoving equipment. If hard

material is encountered controlled blasting may be necessary under strict

management.

• Gravel will be loaded into an adjacent crushing / screening facility.

• When the gravel deposit is exhausted, or gravel from that particular quarry is no

longer required the quarry site will be rehabilitated. This may include the use of

the quarry to deposit excess fill.




48

17. Archaeological and Heritage Management

At the time of consent, no archaeological sites were known to be present and it wasconsidered unlikely that any unrecorded sites would be exposed during construction at the

CHWF Site. However, it is possible that items of archaeological interest may be discovered

as a result of exposing sub surface layers.

To address the potential for discovery items of archaeological interest, a comprehensive

Accidental Discovery Protocol will be developed in consultation with the tangata whenua.

This Accidental Discovery Protocol (ADP) will ensure that if koiwi tangata (human remains),

taonga or sub-surface archaeological evidence is uncovered during construction, work

would cease in the immediate vicinity of the remains so that appropriate action can be

taken.

Should an archaeological site be identified (through the CHWF construction process) and

the modification of such a site become necessary, an ‘Authority to modify an archaeological

site’ shall be applied for under Section 11 of the Historic Places Act 1993. No further work

shall be carried out that will affect the site until the appropriate permissions are granted.

This is in accordance with legal requirements. In addition, the tangata whenua shall be

consulted regarding the effects on Maori cultural values.

All Contractors working on the Site will be required to go through a Site induction process,

which will include training on the accidental discovery of cultural or archaeological sites or

material

A Draft Archaeological Accidental Discovery Protocol is provided in Appendix P.




49

18. Biodiversity Management

The approach to biodiversity management at the CHWF Site encompasses acomprehensive suite of measures that address effects to vegetation, habitats, flora, and

fauna through construction and operation of the wind farm. These are set out in a number of

SEMPs, each of which is summarised below and include for the mitigation of operational

effects.

18.1 Revegetation Plan

A Revegetation Plan will be prepared to ensure that rapid reinstatement of vegetation cover

following on from earthworks. The overall objective of this plan will be to ensure that vegetative cover (or alternative protective measures) is established within 3-6 months of the

completion of Site works. An outline of the Revegetation Plan is provided in Appendix L.

18.2 Habitat Management Plan s)

A Habitat Management Plan will be prepared for the CHWF, to enhance areas of indigenous

vegetation and habitat to improve the overall quality and productivity of that habitat. This

shall address matters such as legal and physical protection by covenant and fencing,

enrichment planting, revegetation planting (if required), natural regeneration, pest control,

and monitoring and reporting. It will guide the permanent protection and ongoing

improvement of an area of habitat approximately 210 ha in size, in a staged manner. An

outline of the Habitat Management Plan is provided in Appendix Q.

18.3 Riparian Protection Plan

A Riparian Protection Plan will be prepared to guide the physical protection of stream

riparian margins. It will establish the mechanism for the implementation of riparian protectionis achieved in a staged manner as the wind farm is constructed.

An outline of the Riparian Protection Plan is provided in Appendix R.

18.4 Weed Hygiene and Surveillance Plan

A Weed Hygiene and Surveillance Plan shall be prepared to promote good weed hygiene

and a high standard of weed control at the CHWF Site. This will address matters such as

transportation risks from vehicles or equipment and cover both terrestrial and aquatic pestspecies. The Weed Hygiene and Surveillance Plan is located in Appendix M and will require:




50

• All contractors to practice good weed hygiene, cleaning their equipment before

entering the CHWF Site.

• Ensuring that aggregates, soil, sand other material brought onto the CHWF Site

is weed-free.

• Ensuring that existing weeds present On-site do not have their spread

exacerbated by On-site activities.

• Measures to reduce the likelihood of an accidental introduction to the extent

practical.

• An annual weed monitoring programme.

• Control measures to address invasive species as a result of monitoring.

18.5 Goat Control Plan

As a component of the approach to managing pests across the Site, a Goat Control Plan

will be prepared to provide a coordinated management approach to the control of feral

goats across all properties associated with the CHWF with an aim to reduce goats to very

low levels and eliminate goats over a period of 5 years.

An outline Goat Control Plan is provided in Appendix S.

18.6 Avifauna Monitoring Plan

An Avifauna Monitoring Plan will be prepared to establish the baseline situation (building on

monitoring already undertaken at the Site) and also provide for the monitoring, assessment

and analysis of the impacts associated with the CHWF. The Avifauna Monitoring Plan shall

establish a mechanism for assessment and review by relevant specialists in order to

determine if any effects on avifauna have arisen as a result of the operation of the wind farm

and the process and proposed measures that shall be implemented to manage such effects

in an adaptive manner.

An outline Avifauna Monitoring Plan is provided in Appendix T.

18.7 Bat Monitoring Plan

Long-tailed bats have been found within the CHWF Site. A Bat Monitoring Plan will be

prepared to address the potential presence of bat roost sites within the construction

footprint, the process for relocating bats should the removal of the roosts be deemed

necessary (including seasonal and breeding considerations) and also measures to




51

determine collision risks, collision monitoring, and the process and proposed measures that

shall be utilised to manage such effects in an adaptive manner.

An outline Bat Monitoring Plan is provided in Appendix U.

18.8 Lizard Monitoring Plan

A Lizard Monitoring Plan will be prepared to provide a mechanism for managing potential

effects on lizards. This will ensure that likely lizard habitat is identified and searched prior to

construction and that lizards found during construction are handled correctly and if

necessary, translocation to an area of appropriate adjacent habitat be made. Only lizards

which are officially threatened will be the subject of translocation efforts.

An outline Lizard Monitoring Plan is provided in Appendix V.

18.9 Predator Control Plan

Predator control will be undertaken at the CHWF to reduce ecological impacts arising from

introduced predators at specific high value locations within the Site. An outline of the

Predator Control Plan is provided in Appendix W.

18.10 Vegetation Management Plan

A detailed assessment of vegetation clearance requirements and mitigation has been

performed and accounted for in the AEE. Included in this is the requirement for an amount

of vegetation clearance/trimming to reduce flow effects on the wind turbines and to

maintain transmission line clearances. Where trees will be felled, this activity will be

performed by suitably qualified tree felling contractor.

An outline Vegetation Management Plan id provided in Appendix X.

18.11 Aquatic Monitoring Plans

In order to determine any effects from construction of the CHWF, a comprehensive

management programme for avoiding or mitigating effects on in-stream values is proposed.

This comprises a Baseline Aquatic Monitoring Plan (BAMP) and a Construction Aquatic

Monitoring Plan (CAMP).




52

The BAMP will be developed to collect pre-construction information on aquatic communities

within the Site and will provide a comparison with subsequent monitoring during

construction.

The CAMP will then be developed, based on the BAMP, and will include compliance

standards and measures to be implemented if standards are not met Any potential effects

will be minimised by adopting best-practice erosion control measures during construction

and prompt post-construction revegetation of disturbed sites according to the ESCP.

It is expected that there will be a combination of culverts and small bridges required for the

Internal Roads to cross watercourses. Conceptual designs for water crossings have been

developed and will be implemented at watercourse crossing sites, to enable fish passage to

be maintained, as discussed in the COMR. Fish located in areas of stream beds which are

likely to become stranded or harmed by construction activities in and around the stream

may be captured and released in a section of stream that will not be affected by

construction activities.

A Draft BAMP is provided in Appendix J and Draft CAMP provided in Appendix K.




53

19. Visual Mitigation

Genesis Energy intends will minimise the landscape and visual effects arising from theinfrastructure at the CHWF by implementing the following:

• Siting Turbines within a defined Turbine Corridor which has been identified to

have acceptable environmental effects.

• Colour turbines off-white to light grey colour using a low reflectivity paint to

minimise visibility of turbines and reduce the potential for blade glint.

• Screen infrastructure (substations, buildings, etc) with appropriate vegetation to

‘soften’ built features in the landscape (where practicable).

• Use an appropriate colour palette for permanent buildings to assist in theirintegration into the landscape using colours recessive in nature, and appropriate

within the rural environment

• Investigate and where appropriate, implement site specific landscape mitigation

where it is considered that the occupants are likely to experience high visual

effects from their dwelling area.

• Work with the CAA and qualified landscape architect to reduce the effects of

light spillage (type, placement, colour) from turbines and other permanent

facilities.

Once wind turbine positions are finalised the assessment of shadow flicker effects will be

reassessed to confirm that predicted shadow flicker effects are less than the guidelines of

no more than 30 hours per year and/or 30 minutes per day. Landscape mitigation shall be

applied where high visual effects will be experienced from dwelling areas (where

appropriate).

Genesis Energy will minimise the landscape and visual effects arising from the earthworks

of the CHWF by implementing the following:

• Briefing construction staff on the desired approach to minimise environmental

impacts and proposed rehabilitation measures.

• Minimise extent of earthworks cuts and escarpments in road creation at final

design.

• Minimise height of earthworks cuts and escarpments at final design where

practicable.

• Engage a qualified landscape architect to assist in minimising visual impacts.

• Modify cut and fill to relate to the existing landform and natural features

• Store and reuse topsoil on finished earthworks to assist in revegetation.

• Revegetate areas on a like-for-like basis




54

20. Hazardous Material Management

A bulk storage facility (or facilities) shall be provided within a suitable location close to Siteoffices or active construction areas. Any facilities will not be located within 50m of a

watercourse. The bulk storage facility will be used to provide fuel to service all the vehicles

On-site, probably by way of mini tanker. Towable tankers may also be used in some

circumstances.

The bulk fuel tank will carry a significant capacity of diesel fuel. The tank will be double

skinned – providing an additional layer of containment should the inner tank rupture. This

tank shall be supplied and maintained by a specialist fuel supplier. Any towable tankers will

be stored in the bunded facility when these are not in use.

Spill kits will be carried in all fuel delivery vehicles (tanker trucks and towable tankers), and

be located at the contractors compound, project Site office, substations and any other

location deemed necessary.

Any fuels for hand held equipment, oils, lubricants and other hazardous compounds will be

stored in a secure facility within the contractor compound and O & M facility and in

accordance with all relevant guidelines and regulations. The small quantities of these

materials will be stored on bunded trays to prevent spillage. The following measures shall

also be required:

• The Contractor will ensure that all personnel using hazardous substances aretrained and qualified to do so.

• An incident report shall be prepared in the event of a spill/incident

• All unwanted materials and empty containers should be disposed of Off-site at

an appropriate landfill

• The Contractor Project Manager (or delegate) shall review and retain copies of

Material Safety Data Sheets (MSDS) which identify the specific requirements in

relation to storage, use and disposal of hazardous substances.

20.1 Contaminated Land

Due to the agricultural setting of the CHWF, there is the possibility of encountering old offal

pits, old sheep dip sites, rubbish pits, metals and other contaminants from historical

pesticide/fertiliser use, spills of fuel or other from storage tanks, effluent pits, and asbestos

in buried building materials. During the various investigations and consultation performed at

the CHWF, no evidence of contaminated land of any type was identified.




55

Should contaminated land be encountered then an approach to management and

containment will be developed in alignment with section 22.2 Discharges of Hazardous

Materials and in consultation with the relevant council(s).

20.2 Waste Management

Covered and secure waste bins will be utilised at the Site. Both rubbish and recycling bins

will be provided and they will be clearly marked and emptied regularly to avoid overflowing.

The construction sites and work areas will be kept in a litter free condition.

All waste material will be transported Off-site for disposal at an appropriately licensed

disposal facility. There will be no On-site burial of waste material.

Surplus material and used oils may be collected for recycling; otherwise such material will

be disposed of at a registered facility.

All vehicles involved in the transportation of waste should be well maintained and waste

products on such vehicles will be well secured to avoid spills or loss.

Contractors shall ensure that no litter or debris can be dispersed from any work site, Site

plant or facilities. The dropping of litter On-site will be expressly prohibited and all people

On-site will be made aware of this requirement.

20.3 Fire Management

The following potential ignition sources at the CHWF have been identified:

• Hot work (cutting and welding)

• Cigarette smoking and disposal of butts

• Catalytic converters on petrol driven vehicles when there is a possibility of

contact with combustible material

• Ground engaging tools

The actions to be implemented to minimise the risk of fire and employ best practice with

respect to fire management include:

• Appropriate signage will be utilised to warn of fire danger

• No fires will be allowed On-site unless in accordance with the Forest & Rural

Fires Act 1977, District Council Regulations and Council Bylaws.

• No firearms will be allowed On-site without the authorisation of the Project

Manager and Landowner. It is noted that firearms may be necessary to




56

implement some Biodiversity Management measures proposed for the CHWF

Site.

• Provision of fire fighting equipment (operative fire extinguishers) on all Site

vehicles and water reserves at construction sites.

• Access to the construction site will be by ‘controlled access’ only.

• The project manager and NZ Fire Service will be notified when high fire risk

construction work is being carried out on Site.

• Dead end roads shall have turn around areas at least 25 metres in diameter to

enable appliance access.

• Investigation into the cause of any fire outbreak and implementation of remedial

actions to ensure no reoccurrence of the event will be required.

• Security staff will monitor and inspect all contractor compounds and areasunder construction after work hours for fire outbreaks.




57

21. Operations and Maintenance Environmental Management

The CHWF will be operational over an indefinite period. Activities On-site during theoperational phase are of significantly lower intensity than during construction, therefore a

detailed management approach for the operational phase requirements of the wind farm is

not considered to be required at this stage.

21.1 Operational and Maintenance Activities

At the end of construction, works will be stabilised and structures completed or

disestablished, and activities will be limited to those required for the long term operation of

the wind-farm. Key operational activities are identified below.

• Wind farm operation – i.e. control and scheduling of electrical equipment, and

dispatch of power.

• Repairs and maintenance activities:

o Turbine maintenance, e.g. regular servicing, including changes of

oils, filters, firmware upgrades, inspections, component

replacements

o Electrical balance of plant maintenance – e.g. electrical outages for

transformer, switchgear, other plant servicing or upgrades

o Civil works– periodic repair of Internal Roads, buildings or laydown

areas to accommodate natural deterioration or degradation

o Minor quarrying may be required for road/civil maintenance.

• Other O&M phase activities:

o Turbine performance testing

o Consent compliance testing and monitoring

o Other e.g. educational visits

Typical operations and maintenance activities, effects and management are identified in

Table7 below.

21.2 Transport Activities

Operational transport activities will involve limited day to day access by wind farm staff and

contractors together with occasional delivery of supplies and components. There may alsobe times when major turbine component replacement is necessary. At these times, the level

of activity and the duration of those activities will vary depending on the type of major

component replacement. Transport requirements will include a requirement to import

OW/OD loads, involve increased staffing and possible disruption to traffic.

Civil maintenance of Internal Roads and Turbine Platforms are expected to require

infrequent grading and restoration of roads and Turbine Platforms or their drainage systems

to maintain the level of intensity required for normal operations activities. These activities

will be intermittent, internalised and will be performed on a scheduled basis.

21.3 Wastewater Management

Toilet facilities will be provided On-site, with holding tanks or septic tanks utilised. Sewerage

will be removed from Site and disposed of at a licensed waste treatment facility in

accordance with the manufacturer’s recommendations and the level of utilisation.

21.4 Operational Noise Management

At all dwellings, the sound levels predicted from operational activities from the CHWF can

comply with the limit recommended in NZS6808:2010. To ensure compliance is achieved,

and to address noise issues which may arise upon commencement of the operation of the

wind farm, the following measures are proposed:

• That noise emissions assessed by NZS6801, NZS6802 and NZS6808, will

comply with limits in the District Plans and with those derived by the method in

NZS6808:2010 as appropriate.

• The noise assessment presented in the AEE will be reviewed prior to theconstruction of the CHWF. This will include a recalculation of the CHWF sound

output once the wind turbine selection has been determined and their operating

parameters are known, and their siting location has been determined. The

outcome of this will be the production of an Operational Noise Assessment

Report, in which it shall be demonstrated that the noise limits of NZS6808 or of

resource consent conditions will be met.

• The sound character of the selected turbines should also be assessed once the

first turbines are installed and commissioned, to ensure that special audible

characteristics are not present, and to allow the manufacturer to rectify any

such problems before the remainder of the CHWF is constructed.




62

• An Operational Noise Management Plan (ONMP) shall be produced, which shall

include a description of the monitoring regime that will be employed to

determine compliance with noise limits (including the location of monitoring

points, duration of measurement, and requirements to report results), andprocedures for handling noise complaints. An outline ONMP is provided in

Appendix Y.

21.5 Wind Farm Decommissioning

It is expected that the CHWF will continue to operate with repairs, refurbishments and

replacement indefinitely into the future. If circumstances arise that cause the CHWF to

permanently cease operations, it will be decommissioned. If decommissioning is necessary

in the future, a specific decommissioning plan will be prepared and the appropriateapprovals will be sought from Council at the appropriate time.




63

22. Incidents

All environmental incidents will be recorded and immediately reported to the Project

Environmental Manager within 24 hours of the incident occurring. The Environmental

Manager will determine the need and timing for reporting the incident to the Councils.

The need for and timing of reports will depend on the seriousness of the incident, Where an

incident or potential incident occurs that is likely to cause significant Off-Site effects on

people or the environment a report shall be supplied to the Council detailing the relevant

facts within 48 hours of the incident occurring. A further detailed report outlining

investigations of the causes and identification of additional preventative measures shall be

submitted to the Councils within 14 days of the incident.

All personnel will be made familiar with the CHWF Contingency Response Plan (below),which identifies objectives and actions to be taken in the event of an environmental

emergency. If a significant ecological, social or heritage event occurs as a result of any

project activity, works in the immediate area will cease and the Project Environmental

Manager will be advised. Consultation with Council will be initiated, experts or individuals

will be engaged to assess the extent of the impact, and a plan for remedial action will be

developed. Remedial work will be undertaken as required and may be subject to inspection

from the Councils.

The incidents register will be kept at the Site office. All personnel working On-site are

required to report any incidents.

22.1 Incident Response Plan

If an environmental emergency or incident occurs On-site, prompt remedial action will be

implemented. Once the situation is controlled and addressed, a review will be undertaken to

assess the effectiveness of the remedial actions employed. The EMP will be updated to

reflect the outcome of any reviews.

Unforeseen events which may result in emergency action being undertaken include:

• Natural Hazards such as earthquake, flooding, extreme rainfall and wind events

• Pre-existing contamination sites

• Operational failures

• Equipment failures

• Ecological disturbances

• Vandalism




64

The following sections discuss the potential incidents which may occur On-site and the

expected response.

22.2 Discharges of Hazardous Materials

In the event of a spill or discharge from fuels, lubricants, and hazardous materials the

following procedure should be followed:

• Evaluate the type of spill, the risks involved and the volume of material

• Stop all operations in the immediate area of concern and remove any ignition

sources

• Ensure appropriate Protection Personal Equipment (PPE) is being used

• If appropriate, isolate the spill

• Contain the spill using a spill kit

• Report the incident to the Project Environmental Manager who will instigate the

Incident response’ including:

o Notification of the Regional Council Pollution Hotline

o Notification of the Consents Manager(s) at the Council(s)

o Notification of the Compliance and Monitoring Officer(s) at the

Council(s)

• Seek appropriate help

• Start cleaning the site

• Waste material will be sent to landfill

• Contaminated soil will be sent to the appropriate facility

• Replace any material used in the spill kit

• Review the cause and response procedures. Amend operational procedures as

necessary.

A Spill Response Plan (SRP) has been provided in Appendix Z.

22.3 Sediment Control

Discharges of sediment may occur where there are failures of erosion and sediment control

devices due to a significant or extreme weather event.

In the event of a sediment discharge the following procedure should be followed:




65

• Identify the issue which is contributing to the discharge.

• Take all practicable steps to improve the quality of the discharge, including:

o

Unblocking any sediment control deviceso Use an approved flocculant in accordance with the ESCP

o Increase detention time in sediment ponds where practicable

o Preventing discharge by blocking discharge outlets

o Determine measures to remove deposited sediments

• Undertake a review of the failure to identify any requirement for repair,

replacement or redesign – such as:

o Increase size of sediment control devices

o Installing additional sediment control devices

o Increase diversion of clean water around exposed surfaces

o Mulch exposed surfaces

The Environmental Project Manager shall notify Council at the earliest possible convenience

to advise of the incident and the proposed approach to mitigating the discharge should

appropriate mitigating measures be appropriate or available.

Where sediment discharges prevent the use of domestic water supplies, an alternative

temporary water supply will be installed and maintained by Genesis Energy until the originalsupply is fit for purpose and consumption. This is likely to consist of providing a tank and

tanker supply to the affected areas.

22.4 Fire

Equipment such as fires extinguishers and fire blankets will be located in the Site office and

within all contractor vehicles. Water carts will be located On-site and will assist with

extinguishing a fire. If a fire cannot be extinguished immediately, the Fire Service shall be

contacted. The Project Manager and Environmental Project Manager will determine thesafety of all persons and property in determining the immediate fire response.

The New Zealand Fire Service will be provided with layout details of the wind farm, including

access points, road network and the location of water sources.

22.5 Noise

Should noise generated from the CHWF and associated operations be the subject of

complaint, the noise generating activity will be reviewed in accordance with relevant




66

standards by the Environmental Project Manager and Project Manager and a decision be

made as to weather to stop that activity.

A review will be undertaken to identify why the activity is considered to produce excessivenoise and if there are practical options to reduce the noise generated or remediate the

noise producing activity. Such options to be considered include:

• Undertaking the activity under alternative climatic conditions

• Undertaking the activity in an alternative location

• Reducing the number of activities being undertaken at any one time

• Using noise barriers to muffle sound

• Repair any damaged or faulty equipment generating the noise.

22.6 Air-borne Particles

Should particles such as dust, cement or other contaminants be identified, measures will be

taken to eliminate the source. This will be achieved by applying water to the source of dust,

covering loads or exposed areas.

Once the situation is remedied, the incident will be investigated to determine how the

situation can be avoided or mitigated going forward.




67

23. Inspection, Monitoring and Auditing

The system for reviewing the environmental performance of the project activities will be

based on regular inspections, audits and sound environmental monitoring programs. These

aspects are discussed in more detail in the following sections.

23.1 Inspections

During construction, weekly inspections will be undertaken by the Contractor and Genesis

Energy Environmental Project Manager to achieve fine scale monitoring of specific

environmental aspects to ensure compliance with the EMP, SEMPs and the relevant

resource consents.

An indication of the environmental aspects requiring monitoring and the frequency of

inspections are presented in Table 8 below. This list is not exhaustive and may be amended

as specific environmental issues arise. In addition to the targeted inspections detailed

below, the contractor will have the responsibility of identifying any non-compliance with the

EMP and SEMPs.

Table 8: Environmental Inspections

Environmental Aspect Frequency as

appropriate)

Erosion and sediment controls – Ensure there are no significant erosion /sedimentation events caused by inadequate maintenance of soil / watercontrol devices

As provided inthe SEMP

Culverts – Ensure the culverts On-site remain free from debris and fishpassage is not restricted

Weekly

Hazardous materials and waste – Ensure all hazardous material and wastestored and handled as per the EMP and the statutory requirements

Weekly

Roads – Road conditions meet required standards and ensure the safetransportation of required material On-site.

Weekly

Site remediation – Stabilisation and revegetation works are successful with nosignificant plant loss

Weekly

Biodiversity – Ensure the no-go zones are left undisturbed. Inspections will alsolook for signs of dieback due to dust or root compaction, weed infestationsand plant disease.

As provided inthe SEMPs

The effectiveness of the inspections will be reviewed and where necessary, the level, scope

and timing of inspections will be improved through the life of the project to ensure the

project achieves the required environmental performance.




68

23.2 Monitoring

Genesis Energy has proposed a range of measures and environmental monitoring to

appropriately address the potential adverse effects of the CHWF development.Management of the CHWF during both the construction and operation phases revolves

around the establishment of this EMP and the associated SEMPs.

In addition, Genesis Energy or its representative(s) will closely and regularly monitor the

construction works. Work will require formal notice to proceed. This notice will not be

issued to the contractor unless Genesis Energy is satisfied that appropriate, compliant

measures to avoid potential adverse effects are either in place or shall be undertaken in

accordance with the management plans, or if not practicable, planned to occur during the

works.

23.3 Auditing

Auditing of performance is central to confirming that the environmental management

measures proposed are implemented, effective and maintained. It is appreciated that

Council representatives will have a role in monitoring and auditing the project so that it is

proceeding in compliance with resource consents. In addition to Council monitoring and

auditing (where Genesis Energy will work closely with the Council representatives), Genesis

Energy will have its own audit procedures to ensure that the Contractor engaged to

construct the CHWF is undertaking its work in consistency with Genesis Energy’sEnvironmental Values.

The Project Environmental Manager will be the lead Genesis Energy representative to audit

and inspect works to determine if the contractor is undertaking these in accordance with the

EMP and SEMPs. The Genesis Energy Project Environmental Manager will also undertake

periodic audits in response to complaints and incident management.

23.4 Non-compliances

A Non-compliance Report will be generated when:

• A complaint is received regarding any environmental impact or aspect caused

by the project, provided initial investigations show the complaint is valid.

• A departure from approved or agreed environmental procedures is observed.

• A non-compliance is identified as a consequence of any self assessment, formal

audit or other environmental survey or inspection.




69

Any individual working On-site may create a Non-compliance Report. If the non-compliance

is considered to be a breach of the resource consent or legislative requirements the

Councils will be notified. Non-compliances and corrective actions will be recorded and kept

at the Site office and included in the weekly and monthly reports.




70

24. Complaints and Enquiries

There are several ways the general public can register complaints about the environmental

performance including:

• A dedicated public enquiry line

• Direct contact with Genesis Energy (0800 436 946)

• Direct contact with On-site staff or Project Manager

• CHWF Website by contacting [email protected]

Any complaints received will be recorded by the Project Environmental Manager in the

Public Enquiry Record and registered with the Site Manager. The Record shall include thedetails of the complainant, date, nature of complaint, weather conditions at the time of the

event (if relevant), corrective action and follow up with the complainant. The record will be

kept at the Site office and included in the weekly and monthly reports.

If a material complaint is received the Councils will be notified within 5 days.




71

25. EMP Documentation

The following section describes the documentation required to implement and maintain the

EMP. Genesis Energy will prepare a reporting template which will be issued to Council on a

monthly basis during construction and as necessary during operation of the CHWF.

In addition to the documentation described in the preceding sections, the following

documents will be maintained in the Site office:

• EMP

• SEMPs

• Resource Consent documentation

• Training and induction records

• Any special permits or approvals required to undertake works On-site (e.g.

blasting approvals)

25.1 Work Instructions

The main contractor will prepare Work Instructions where appropriate. Work Instructions will

provide a high level of detail on the environmental aspects and obligations for a specific

work package to guide the relevant personnel or sub-contractors. The scope of the work

instruction will be dependent on the activity being undertaken, and will be prepared at the

discretion of the Project Manager. Examples of environmental aspects requiring Work

Instructions include the following:

• Clearing and internal road preparation

• Removal of, or works around sensitive ecology

• Excavations

•

Weed control• Traffic management

• Waste management

• Soil erosion

• Handling and storage of hazardous substances

• A copy of all Work Instructions will be maintained at the Site office.




72

25.2 Inspection and Audit Reports

As outlined in Section 23 regular inspections and audits will be undertaken and

documented. Inspection reports and associated environmental documentation will beavailable at the Site office. Subsequent details of corrective action and results will also be

available.

25.3 Weekly and Monthly Reports

Weekly and monthly reports will be prepared by the contactor and be made available to

relevant stakeholders. The contents of the reports would include at minimum:

• Monitoring undertaken

• Works undertaken in the work period

• Mitigating measures / management solutions implemented

• Environmental incidents report summaries

• Environmental statistics

• Environmental non-conformances

• Issues, actions

• Any audit reports during the period

A copy of the weekly and monthly reports will be maintained in the Site office. Regular

reports will be provided by the contractor outlining details and performance of management

solutions implemented during the reporting period, and also identifying any improvements or

adaptations to the SEMP required to address any site-specific issues which arise.

1.0 Introduction

This section will provide a brief introduction to the Erosion and Sediment Control

Plan(s) (ESCP) and its purpose in the context of the Castle Hill Wind Farm (CHWF).

The will include a brief overview of the Project, what the project entails and how

ESCPs play a part in the wider suite of management plans for the Project.

The introduction will include discussion of the process to be followed in development

and implementation of ESCPs:

• that Genesis Energy’s contractor/consultants will prepare the detailed design

plans for erosion and sediment control devices as per the direction provided

by the ESCP and the conditions of Resource Consent(s).

DR

A FT

• that the ESCP and detailed design plans will undergo a consultation/review

process with Council.

• that once agreed and consented, the ESCP will be constructed.

• that Genesis Energy and its contractors will be responsible for managing the

operation and maintenance requirements of the ESCP.

1.1 Purpose

The purpose of an ESCP is to describe the method(s) to minimise soil erosion and the

treatment of sediment laden overland flow during construction of the CHWF Project.

This includes, but is not limited to:

• Providing an outline of the proposed activities for each phase of development.

• Evaluation of, and reporting on, activities and monitoring from the previous

phases of development.

• Providing specific details of the earthworks and key associated erosion and

sediment control measures proposed.

The ESCP will be developed in phases consistent with the development of theWindfarm.

1.2 Objectives

The following operational objectives will be used to develop each ESCP.

• The use, as a minimum, of the erosion and sediment control methods

promulgated through the Hydrology Effects Assessment (PDP, 2011) and any

outcomes defined through the required statutory process.

• Demonstrate how the erosion and sediment control methods promulgated are

the Best Practicable Option.

A023373 00R007 Eros ion and Sedi ment Cont rol Plan D raft v2 1





• Review of monitoring data and lessons from implementation of previous ESCPson site to inform the choice of devices used in different situations.

• The ESCP is monitored, evaluated and where necessary modified to manage

or mitigate alterations to the following; the project brief, the project site

conditions or identified risks, or any significant adverse effects identified

within receiving environments.

2.0 Design Philosophy and Principles

The following section will set the context for the development of the ESCP(s). The

principles of an ESCP are defined from Wellington Regiona l Council’s (WRC) Erosion

and Sediment Control guideline (GWRC, 2002). These are:

DR

A FT

• Minimise Disturbance

• Stage Construction

• Protect Steep Slopes

• Protect Waterbodies

• Stabilise Exposed Areas Rapidly

• Install Perimeter Controls

• Employ Detention Devices

• Make Sure the Plan Evolves

• Inspect

These principles will be discussed individually and commentary will also be given how

each should be incorporated within this ESCP.

Reference will also be made to other supporting AEE documentation which outlines the

specific details of each construction location.

3.0 Planning Framework

This is a brief section that will discuss the linkages of the ESCP with the resource

consent(s), required management plans and relevant planning documents.

4.0 Assessment of Risk

The purpose of this section is to provide an analysis of the expected and foreseen

risks that might occur within the area of work being considered.

A project wide risk assessment has been carr ied out and this would be the starting

point for the site specific assessment for the proposed area of work.






The Universal Soil Loss Equation (USLE) would be utilized. This assessment willprovide an initial justification to the proposed sediment and erosion control devices

that will be used to manage and mitigate the effects. This would be confirmed with

the operational experience offered by Genesis Energy’s consultants, contractors and

Council reviewers.

As well as USLE methods, degree of risk can be classif ied into three key categories,

which are:

• Sediment generating potential - this highlights the generation potential of the

area in question and is based on slope, slope length, soils, rainfall and erosion

control factors.

• Sediment delivery – this relates to the amount of eroded material that is

retained on site in depressions and within the site’s natural contours prior to it

entering any sediment treatment devices.DR

A FT

• Sediment yields – the amount of sediment that actually leaves the site and

enters the receiving environment. It is well recognised that this is the key

area of interest.

Discussion of each of these categories will be prov ided in relation to the methods

proposed.

5.0 Overall Erosion and Sediment Control Approach

The following section will provide an outline of the key measures that will be

implemented as part of the ESCP for the phase of work being considered and builds on

the principles outlined in Section 2.0.

5.1 Team Approach

This section will outline the parties and personnel involved in developing,

implementing, monitoring and modifying the ESCP. This will include Council, Genesis

Energy consultants/contractor, and Genesis Energy staff. This section is included to

demonstrate that adequate resources, commitment and expertise are provided to

effectively implement erosion and sediment controls from start to finish of the Project

(design through to dis-establishment).

A key focus of this section wil l be how effective communication will occur. Discussion

on how information, reports, data will be disseminated amongst all the required

parties will be provided.

5.2 Erosion and Sediment Control Device and Measures

This section will provide a brief summary of what erosion and sediment control

measures will be used to minimise the extent of soil erosion and sediment yield in the

area of the site being considered. This will draw from the toolbox of methods set out

in the PDP Hydrology Effects Assessment.






This section will include both engineered (device orientated) and management options(such as staged works, timing of works etc). The section will not get into the specific

detail for each individual device (this comes in section 6), the purpose of this section

is more to state how the device designs will generally conform to meet WRC’s erosion

and sediment control guideline.

5.3 Monitoring

This section will be broken into two types of monitoring; performance monitoring of

device effectiveness, and site monitoring for assessing current and new risk.

Within each of these types of monitoring, discussion will be provided on how the

monitoring results will be reported, evaluated and where appropriate actioned (eitherthrough changes to the monitoring strategy or site erosion and sediment control

improvement). DR

A FT

For device performance monitoring, discussion will be provided to demonstrate that

the erosion and sediment control devices have been installed correctly and are actually

working as intended. This monitoring section will need to demonstrate what

procedures will be used throughout the entire period of construction.

Discussion of the performance monitoring information of erosion and sediment control

devices will be provided.

Discussion of how monitoring will be undertaken; such as grab samples, laboratorymethods of analysis, reporting of monitoring results, and how monitoring results will

be evaluated and where appropriate, the monitoring methodology altered, will be

provided.

In parallel to device monitoring, receiving environment monitoring of freshwater and

freshwater habitat monitoring will be included.

The monitoring section will also include how continued assessment for risks will be

undertaken i.e. risks that were not identified initially, but may become apparent over

the construction period. This is essential to cover the principle regarding plan

evolution and improvement. Discussion on what mechanisms will be in place to

incorporate newly identified risk into the ESCP will also be provided.

5.3.1 Response to Indicators of Significant Effects

In this section, discussion will be made as to how parties will respond to adverse

events and what measures will be in place if adverse effects are detected.

This section will include discussion that should linkages between the adverse effect

and on-site erosion and sediment control practices be found, then alterations to the

operational methods (including modifications to environmental control measures and

methodologies) will be investigated as a first order response.






5.4 Miscellaneous Activities

This purpose of this section will be to provide discussion of the effects caused by

miscellaneous activities. Discussion will need to be included how these miscellaneous

activities will be managed. For example, dust management from roads and any

further site specific monitoring will be discussed.

6.0 Specific Erosion and Sediment Control Methodology

for Defined Areas

This section will provide the detailed methodology regarding the erosion and sediment

control methods to be implemented in the area of works under consideration.

DR

A FT

Summary information regarding the devices within each phase of development will be

provided. Information such as; catchment area draining to the device,

pond/channel/bund volume, (forebay volume), the number of decants, side slopes,

and associated drawing references, will be provided.

6.1 Development Area 1






7.0 Activity Details and Methodologies

This section will provide detailed information for the more specific ‘higher risk‘

activities within the project. For each of the below, discussion will be provided

regarding the activity, and how erosion and sediment control will be undertaken for

these areas.

The following sections provide some of the potential ‘higher risk’ activities that will be

discussed.






7.1 Roads in steep topography

7.2 Concrete Batching Plants

7.3 Stream Realignments and Rehabilitation

7.4 Quarries

7.5 Culvert Installation

7.6 Bridge Works

8.0 Planning Considerations

This section is set to link back to the earlier Section 3 where relevant statutory

documents were identified that are associated with this Plan. This section will

therefore discuss the assessment whether the proposed ESCP meets these statutory

provisions within the identified documents.

DR

A FT

The purpose of this section is to demonstrate to stakeholders that the ESCP is

satisfactory and meets the relevant statutory documents.

8.1 Assessment against the Statutory Provisions

Commentary for each of the above described assessments will be placed here.

1.0 Introduction

This section will provide a high level discussion summarising the purpose of the

Drainage Management Plan (DMP) and how the DMP plays a part in the wider suite of

management plans for the Castle Hill Wind Farm (CHWF) Project.

The introduction will include discussion of the process to be followed in development

and implementation of the DMP:

• that Genesis Energy’s consultants will prepare the drainage detailed design

plans for each individual device or structure as per the direction provided by

this DMP and the Consent.

DR

A FT

• that these detailed design plans will undergo a consultation/review process

with Council.

• that once agreed and consented, the drainage network will then be

constructed.

• that Genesis Energy will be responsible for managing the operation and

maintenance requirements of the drainage network as directed by this DMP.

1.1 Purpose

The purpose of the DMP is to outline the proposed designs for proposed permanent(operational phase) drainage devices and structures for the Castle Hill Wind Farm

(CHWF) project. This includes, but is not limited to:

• Outlining the proposed infrastructure that will used to manage stormwater

effects (flooding and water quality management) during the operational phase

of the CHWF Project.

• Provide details as to how the proposed infrastructure will be designed,

operated, maintained, and monitored to ensure that stormwater effects from

the project are appropriately managed.

The DMP may be developed progressively in line with future construction phasing ofthe CHWF.

1.2 Objectives

The following objectives will be used in the development of the DMP.

• The use, as a minimum, of the methods promulgated through the Hydrology

Effects Assessment (PDP, 2011) and any outcomes defined through the

required statutory process.

• Demonstrate how the designs and methods promulgated are the Best

Practicable Option and meet the design requirements.

A023373 00R006 Dra inage M angement Plan Draft v2 1





• Review of any monitoring data and operational lessons from implementationof previous parts of the DMP on site to inform the choice of devices used in

different situations.

2.0 Design Philosophy

This section identifies the key drainage requirements set out in the Hydrology Effects

Assessment and wi ll set out the methodology used to generate the proposed drainage

works for the Project.

Table 1 below, provides the recommended design criteria for the project.

In addition to the recommended design criteria, linkage to the statutory requirementsof the Resource Management Act 1991, will also be made. Here, as a minimum, the

following objectives can be included: DR

A FT

• To minimise any potential adverse environmental effects on water quality and

aquatic ecosystems from the proposed stormwater discharge from the Project.

• To minimise any potential adverse environmental effects from flooding or

erosion (inclusive of land or watercourses) from the proposed stormwater

discharge of the Project.

Any specific consent conditions relating to drainage wil l be identified here.

Table 1: Recommended Drainage Design Criteria

Infrastructure Design Criteria

All culverts shal l be designed to pass the peak flow during the 20 year ARI event. The bank full flow shal l be passed without becoming theculvert becoming inlet controlled.

All culvert designs for watercourse crossings shall allow for the passageof aquatic fauna (e.g. fish and invertebrates) and fauna (e.g. waterdispersed seeds and pollen).

Culverts

Culvert structures shall be designed with good practice with respect to;

erosion and sedimentation around outlets, blockage of inlets, provisionof secondary flow paths or secondary inlets, flood hazard, and operationand maintenance requirements.

Primary piped systems shall be designed to convey the peak flow fromthe 20 year ARI event.

Site Drainage

Secondary overland flow paths shall be designed to convey the peak flowfrom the 100 year ARI event based on the assumption that the primarypiped system is not operating (i.e. due to blockage, damage etc).

All new industrial floors and sub-station yards shall have a minimumfreeboard of 1.0m above the 100 year ARI event water level (measuredto the underside of the floor structure or yard finished level).

Flooding

Works shall not exacerbate flooding of existing buildings.






DR

A FT

Table 1: Recommended Drainage Design Criteria

Infrastructure Design Criteria

Climate Change Climate change shall be factored into the estimation of peak flows fromdesign events.

3.0 Drainage Effects

The following section will provide discussion and analysis of the surface water effects

the DMP will manage or mitigate. This can be broken down into the following

subheadings.

3.1 Water Quantity

Discussion of the effects of flooding within the project location will be provided.

3.2 Water Quality

Discussion of the effects of contaminant management/mitigation within the project

location will be provided.

3.3 Ecology

Discussion of how that DMP will be used to manage ecological function within the

project location will be provided.

The above discussions will include the need for drainage networks to be cognisant of

aquatic ecological functions. An example of this is to ensure the design of drainage

networks that enable fish passage, stormwater outfall protection etc.

4.0 Design and construction of the drainage network

This section is a significant component of the plan.

This section will firstly state that the design of these drainage devices is aligned with

the design philosophy that was discussed earlier in section 2, and be designed to

achieve management or mitigation of the effects discussed in section 3.

Following this, details of the design and any specific construction requirements for the

relevant type of drainage device or structure will be provided.

In this section, the design discussion is not for each individual device, but should

describe the methodology that was undertaken to design/size the device type.

Similarly, the construction discussion will summarise the fundamental construction

considerations that need to be addressed when constructing each device type within

the project.






Calculations and detailed design plans for each individual device or structure will beprovided as appendices. Appendices will be titled for each device/structure type.

5.0 Operation and Maintenance Procedures

This is another significant component of the plan. This section will provide detailed

discussion of how the drainage infrastructure will be operated and maintained over its

lifecycle.

Details regarding inspection frequencies will be provided. Maintenance frequencies will

include scheduled or routine maintenance procedures and also major or reactive

maintenance procedures.

A l ist of the people with defined roles and responsibili ties for operation andmaintenance will be provided and who is going to be people involved to ensure that

the DMP is effectively implemented, monitored and when appropriate modified to

ensure best practice operation and maintenance methods are maintained.

5.1 Culverts

5.2 Bridges

5.3 Long term channels

5.4 Overland Flow Paths

5.5 Secondary Overland Flow Paths

5.6 Water Quality Devices

In the previously discussed appendices, where appropriate, maintenance inspection

check sheets for each device/structure type will be provided.

5.7 Response to Operational Drainage Problems

This section will specifically discuss how operational problems relating to the drainage

network will be mitigated. Here, the strong linkages to the spill response plan and

also the erosion and sediment control plan will be discussed. A listing of key contacts

from outside the operation and maintenance team who can be contacted regarding

significant issues will also be provided.






5.8 Training

This section will outline any training that may be required to ensure that the operation

and maintenance requirements of the DMP are achieved.

6.0 Plan Review and Evaluation

This section will set out how the DMP will be monitored, evaluated, and where

appropriately reviewed and modified. This section would have reference back to

Section 3, where the objectives identified there will be used to determine whether the

DMP is being effective or if modification is required. The section will discuss the

frequency this occurs and what procedures will be undertaken.

natural watercourses. The schedule should include, but not be necessarily

limited to, descriptions of proposed bunds, sumps, diversion channels, storm

water treatment ponds, weirs, spillways and vegetated storm water disposal

strips.

control is to minimise the amount of contaminants that will be discharged onto

land, the air, or into natural watercourses.

• Schedule of hazardous substance control measures. The schedule shall

include, but not be necessarily limited to, control measures for storage of fuels

and oil.

• Schedule of dust control measures. The schedule shall include, but not be

necessarily limited to, descriptions of water spraying or water misting.

programme for monitoring storm water discharge for pH and suspended

sediment.

• Contact details for Contractors and relevant Genesis Staff

It is anticipated that many (or potentially all) of the concrete batching plants will be adjacent

to, or contained within a quarry. Where this is the case, then the environmental measures

taken in the quarry and concrete batching plant will be closely interlinked. In such

circumstances the QMP shall be prepared, and incorporate environmental measures for the

concrete batching plant.

Where a concrete batching plant is planned separate from a quarry, then a CBMP shall also

be prepared.

An indicative sketch layout of the quarry is provided below.

Appendix J: Baseline Aquatic Monitoring Plan BAMP)

Purpose

To guide the collection of pre-construction information on water quality and aquatic

communities within the Castle Hill Wild Farm Site (CHWF) to ensure that standard

compliance can be adequately assessed during construction.

Objective

To provide the information needed for the development of compliance standards for water

quality and biological parameters to be included in the CHWF Construction Aquatic

Monitoring Plan (CAMP).

Proposed content

• A review of Council surface water quality and biological parameter standards to

identify those relevant to construction of the CHWF (e.g. current (July 2011)

Horizons and Greater Wellington Regional Council water quality standards are

listed in Tables 1 and 2, below).

• Determination of baseline monitoring required allowing assessment of

compliance with standards during construction. This may include a requirement

to collect information on flow rates or rainfall.• The selection of appropriate monitoring sites that are representative of the

receiving water and will allow compliance with standards to be assessed during

construction. This requires information on key construction locations (e.g.

access road routes, watercourse crossings, water intakes, turbine and

infrastructure locations, and spoil disposal sites) to enable sites to be chosen in

the most appropriate locations. Factors to consider in the selection of sites

include ease and safety of access, positioning in relation to Council defined

mixing zones downstream of discharges or instream works, and the inclusion of

unaffected upstream reference sites where possible. Consultation with the

relevant Council is recommended during this process.• A detailed method for the collection of any required baseline monitoring

information. Including the identification of suitably qualified personnel, a

timetable stating when sampling should begin and end and the timing and

frequency of sample collection, a list of parameters to be measured (e.g. pH,

temperature, dissolved oxygen, water clarity, QMCI, etc.), the method of

sample collection and processing to be used, and a format for the recording and

reporting of information.

• The requirement for the preparation of a report to be provided to the relevant

Council stating what water quality and biological parameter standards will be

included in the Construction Aquatic Monitoring Plan (CAMP) for assessment




of compliance during construction and, where necessary, the baseline values

against which the standards are to be assessed.

Genesis Energy, Castle Hill Wind Farm: Construction Traffic Management Framework

ctmp



1

1. Introduction

This document is the Construction Traffic Management Framework for the Castle Hill Wind Farm.

It has been prepared to set out the purpose, objectives and specific standards to be applied when

preparing the Construction Traffic Management Plan (CTMP) at the detailed design stage.

Some aspects of the construction methodology are to be fixed as specific standards in this

Framework which must be included in the CTMP under the conditions of the resource consent for

the CHWF. Other aspects, such as timing and staging (which influence traffic volumes), are to be

developed at the detailed design stage when contractors are involved. It is not practical to

prepare these details at this stage, and the approach of preparing the full CTMP at the detailed

design stage will enable contractors to bring innovation where appropriate, enabling a

substantially better outcome for other road users, the efficiency of construction, or both.

The CTMP is to be prepared by a Chartered Professional Engineer with specialist skills in Traffic

Engineering and Transportation Planning, appointed by the consent holder. Preparation of theCTMP will involve input from the principal civil engineering contractor, the turbine transport

contractor, Tararua and Masterton District Councils, residents on the transport route who wish to

be involved, emergency services and local transport operators (such as the school bus operator

and livestock transporters). It will be required to meet the purpose, objectives, and specific

standards set out in this Framework. The Plan is to be submitted to the Councils to be assessed

and certified as meeting the requirements of the Framework.

2. Purpose and Objectives

2.1 Purpose

The purpose of the CTMP is to set out in detail the manner in which construction traffic will be

managed to ensure the safe and efficient performance of the road network, to minimise adverse

effects on the existing community arising from construction traffic, and to provide the community

with information about Genesis Energy’s traffic arrangements.

2.2 Objectives

These objectives will be achieved by the methods set out in the CTMP.

3. CTMP Development Process

Preparation of the CTMP will be facilitated by a Chartered Professional Engineer, specialising in

Traffic Engineering and Transportation Planning, appointed by the consent holder. Its

preparation is to begin approximately four months before construction.

In preparing a first draft CTMP, the Chartered Professional Engineer shall:

(i) review this Construction Traffic Management Framework;

(ii) review the CHWF Transportation Assessment and relevant evidence;

(iii) review the approved consent conditions;

(iv) liaise with the consent holder, the lead civil engineer, the principal civils

contractor, the turbine transport contractor, Tararua and Masterton DistrictCouncils, residents on the transport route who wish to be involved, NZ Police, NZ

Fire Service, St Johns Ambulance, the school bus operator, rural transport

operators (identified by residents), and vets.

Liaison may involve such meetings and conversations as are appropriate to ensure effective

consultation with the parties listed above, and others considered appropriate by the Engineer.

The first draft will be circulated to the above parties for comments and suggestions. A period of

at least four weeks will be allowed for comments and suggestions. These will be evaluated by

the Chartered Professional Engineer and incorporated into the completed CTMP, as the Engineer

determines appropriate.

The completed CTMP will be submitted to the Tararua and Masterton District Councils at least

four weeks before construction of the CHWF begins along with a report outlining the comments

and suggestions made on the first draft, and the extent to which they have been included. The

Tararua and Masterton District Councils will assess the completed CTMP with a view to certifying

it as meeting the purpose, objectives, and specific standards set out in this Framework.

Any changes required to achieve that certification will be discussed between the Councils and the

Engineer and made, enabling the final CTMP to be distributed to:

(i) the consulted parties;

(ii) rural transport operators and rural service providers who regularly use the primaryaccess roads; and

(iii) made available to residents and others who have an interest via electronic media.

Updates will likely be required from time to time as a result of project changes or issues arising,

which may be identified by the consent holder, its contractors, Tararua or Masterton District

Councils, or to address matters relating to residents or other road users. Suggested changes to

the CTMP or issues arising will be referred to the Chartered Professional Engineer who will

consider the matter and make a recommendation to the Tararua and Masterton District Councils.

If the Councils certify the recommended changes to the CTMP, revised copies will be made

available via digital media for the above referenced parties.

4. CTMP Content

The CTMP is to include, as a minimum, the following content.

4.1 Consent ConditionsThe CTMP shall record the full set of consent conditions relating to traffic and transportation

conditions in this section. The following specific actions and responses shall be developed

having regard for the consent condition requirements and the bases on which the Transportation

Effects Assessment has been made.

4.2 Construction Programme

The CTMP is to present the confirmed construction programme, setting out the start and end

dates for the key traffic generating activities. From this, all parties will be able to understand the

type of activities that are occurring and therefore the types of vehicles to expect on the roadnetwork.

4.3 Traffic Flows

Based on the programme and construction methodology, the CTMP will set out the expected

profile of average daily truck and light vehicle movements from month to month during

construction. It will also address the expected spread of traffic throughout the day, considering

the arrangements for transporting materials and people to the Site, including the geographic

spread of sources and accommodation.

4.4 Road Safety Assessment

An assessment of the road safety record as contained on the Land Transport New Zealand Crash

Analysis Database for the most recent five year period shall be provided, and commentary given

on any particular road safety matters that warrant consideration. Where relevant, this may be

taken from the Transportation Assessment Report and updated.

A visual assessment shall also be made of the Local Roading environment to determine the

nature of road safety. Any potential notable risk areas shall be identified and recorded in this

report along with the mitigation planning to be implemented.

4.5 Wind Farm Access Points

The CTMP will provide details of the individual points where the Site will be accessed from the

public road network including how security will be managed.

4.6 Travel Routes

The CTMP will map the travel route(s) to be used by construction vehicles and for oversize loads

travelling from the receiving Port.

(vi) fertilising activities in autumn and spring. Of note in this regard is the Daggs Road

access to the airstrip, which appears to service up to about seven farms.

4.8 Travel Plan

A Travel Plan shall be developed to minimise contractor generated traffic and construction traffic

movements to and from the Site. This shall consider for example alternative travel modes, off-set

travel times, ride sharing and opportunities for back loading of construction vehicles.

4.9 Driver Protocols

In addition to the driving standards imposed by law, all drivers involved in the project will besubject to additional protocols when travelling along the district roads. The objective of these

protocols will be to ensure the safe operation of roads and to minimise existing user delay during

construction.

The CTMP will set out these protocols along with the monitoring and disciplinary procedures to be

followed in the event of any breaches.

4.10 Contractor Parking

Contractor parking is to be planned to be wholly accommodated On-Site and clear of the public

roads. The location, quantity and provision of parking is to be specified in the CTMP todemonstrate the suitable provision and location of the activity.

4.11 Oversize Loads

The CTMP will address the movement of Over-weight and Over-dimension loads. While this

work will be undertaken by specialist contractors operating under permits specific to the project,

the details will be repeated in the CTMP to inform interested parties in understanding what to

expect.

This part of the CTMP is to include:

Appendix Y: Operational Noise Management Plan ONMP)

Purpose

The purpose of this Operational Noise Management Plan (ONMP) is to describe the means

by which noise effects arising from the operation of the Castle Hill Wind Farm (CHWF) will

be avoided, mitigated or remedied, to describe the means of monitoring compliance with

noise conditions, and to describe a mechanism by which any noise complaints related to

Operation will be received and addressed.

Objectives

The objectives of this ONMP are as follows:

• Describe the noise limits which apply to noise sensitive locations near the Wind

Farm.

• Describe the activities which will produce noise at dwellings, and describe the

likely noise levels times for which this will occur.

• Describe the method of monitoring noise levels to ensure that noise limits are

met.


the community of operational activities and to receive and respond to any

complaints.

• Describe a procedure for response to complaints.

• Describe the responsibilities of the Wind Farm operator in reporting to the TDC

and MDC.

Proposed Content

Noise Limits

The noise limits which apply to this Wind Farm are described in detail in the FinalOperational Noise Assessment Report (FONAR). In general the limit on noise from wind

turbines is 40 dB LA95 at the notional boundary of dwellings, although at x specific

locations this limit rises with increase wind speeds as discussed in the FONAR.

Noise from vehicles on Site and fixed plant including substations and etc are those

described in the Conditions of Consent, which relate to the permitted activity noise limits in

the District Plans.

Noise Producing Activities

Wind Turbines




Noise is produced by wind turbines when they operate, with noise output level depending

on wind speed. The wind turbines used in the CHWF are xxx model yyy which produce a

peak noise output of xx dB Lw. The turbine operate in the wind speed range of xx and yy.The operational mode of the turbines are xx during condition A and yy during condition B.

Substations

On-site Vehicles

Maintenance Facility Activities

Others as Applicable

Noise Monitoring

Noise monitoring for compliance testing purposes shall be carried out within xx months of

the completion of the Wind Farm, [or of each stage of the wind farm… details to be

determined]. All noise monitoring shall be carried out in accordance with the relevant

clauses of NZS6808:2010, and compliance testing shall be reported in accordance with the

requirements of that standard.

Liaison

Ongoing communication between the Council and the Community and Genesis Energyforms a useful part of the management of noise effects and provides input into any future

review of consent conditions.

Complaint history shall be maintained by TDC and MDC and made available for

consideration upon request.

A 6-monthly newsletter shall be placed in the local newspaper by Genesis Energy during the

first two years of operation. The newsletter shall include updates on the development and

operation of the wind farm, results of compliance testing, and shall provide contact details

for the Community to communicate with Genesis Energy.

Complaints Procedure

Any noise complaints may be directed to the Community Liaison Manager.

Complaints shall be responded to within 24 hours. The response shall include an

investigation of the noise produced at the time of the complaint, and if compliance with

consent conditions is uncertain, shall be accompanied by a noise assessment to determine

what, if any, additional mitigations should be implemented.

The result of the noise assessment shall be reported back to the complainant within xxhours of a determination of the response.




Procedures for Investigation of Complaints

Prior to the receipt of Compliance Testing Report

Complaints may be received in the first months of operation of the Wind Farm, prior to the

completion and reporting of compliance testing. These complaints may be relevant to

compliance testing, and Genesis Energy shall direct its noise consultant to have regard for

these complaints and the conditions in which they arise in the compliance assessment.

Within three working days of receipt of such a complaint Genesis Energy shall provide a

written or emailed response to MDC and TDC advising that this information has been

provided to its noise consultant, and an estimate of the date of completion of the

Compliance Testing Report, or any other relevant information about the status of

compliance testing.

The Compliance Testing Report when submitted to the Councils shall include a section

discussing complaints received, and describing the actions taken to incorporate these

complaints into the assessment methodology.

Following the receipt of Compliance Testing Report demonstrating compliance)

Complaints received after the Wind Farm has been demonstrated to be compliant with

Consent Conditions may arise from one of two causes:

1. Operational conditions exist which were not considered in the assessment of

compliance. This may include a change in noise emissions due to wear or failure of

turbine components, or meteorological conditions which were not foreseen, or

some other change to the wind farm.

2. Resident satisfaction is not addressed by confirmation of compliance with consent

conditions.

On receipt of a complaint it may not be possible for the Council to determine which of these

two categories the complaint falls into. When each complaint is passed to Genesis Energy,its first response shall be to report the wind direction, wind speed, and number of

operational turbines at the time of the complaint to the Council, and to provide a statement

as to whether this set of conditions has been demonstrated to be compliant.

Where conditions arise which have not been considered in the Compliance Testing Report,

a suitably qualified and experienced person shall be engaged to assess compliance under

these conditions. The results of this assessment shall be provided to TDC and MDC. If non-

compliance is demonstrated, remedial steps shall be undertaken as described in the

following section. If compliance is demonstrated, then this condition shall not be required to

trigger such an investigation following future complaints under similar conditions.




If a number of complaints are received during a specific period under a condition which has

previously been shown to comply, the Council may request Genesis Energy to provide

evidence (for instance by comparing sound levels near the turbines to those levels

produced during compliance testing) that the wind farm noise output has not increased aftercompliance testing was carried out.

If a significant increase is demonstrated under the wind conditions in question, the Council

may request that compliance testing be repeated for that wind condition. If the sound level

has not increased by more than 2 dB, then the relevant complaints may be considered to

belong to category 2 above. In this latter case the complainants shall be informed that the

wind farm has been deemed to be operating within its consent conditions, but that the

complaints have been permanently logged and will form part of the complaints record.

Following receipt by Councils of the required description of operational conditions and

intended actions by Genesis Energy (including a timeframe for these actions), a written

response shall be provided to each complainant describing this action. This response shall

be provided within one week of the complaint. It is acknowledged that if the noise event is

caused by unusual meteorological conditions, the timeframe for assessment of that

condition may be dependent upon these conditions re-occurring.

Remediation Measures

Should non-compliance be demonstrated, the operation of the wind farm shall be ceased or

modified until modifications are made to reduce noise. These modifications may include

modifications to turbines, cessation or modification of operation of certain turbines duringcertain wind conditions, or improvements to sound insulation at affected properties, or

other treatments.

Resumption of operation shall be subject to the demonstration of compliance. Prior to the

re-commencement of operation, a report shall be provided by Genesis Energy to

TDC/MDC describing the remedial steps taken and demonstration of compliance.

This information shall be reported to the complainant(s) who were affected by the original

noise event.
